What is something that gets a lot of hate for absolutely no reason?

Cycle infrastructure, even.

Bike lanes are car infrastructure. We cyclists are perfectly within our rights to cycle in the middle of the lane at a speed comfortable for us. And it's safer for us to do that than hug the shoulder and risk getting clipped by an impatient driver. A bike lane gets us out of your way so you can drive the speed limit. It's for your benefit.
- That's why it's hate for no reason!
  The same hatred from the same haters for public transport too: if everyone else is in public transport there more room for you on the road.
  It's a bizarrely prevalent attitude from a bizarrely large portion of car users.
  We had some nice mini-traffic island things separating a cycleway on a road, drivers kept hitting them and damaging their cars. They complained and the council removed them despite it being obvious to anyone that they were doing extremely what they were supposed to do: stopping those idiots from hitting actual cyclists!
- Holy words
- I thought this as well but German drivers will dangerously swerve into oncoming traffic to overtake me sometimes when I block a lane. Even if there is a red stop light 50m down the road.
  
  Well, it's less of them, and at least they're risking their own lives too. If there's an accident I want the person responsible coming with me to the hospital. That might not be rational, but it's how I feel.
  
  Lol it's not rational but I know how you feel. Sometimes I daydream somebody hits me and wrecks my bike and then feels so bad that they give me loads of money in hopes of me not suing them, and then I use that to buy a better bike. And then I wonder wtf is going wrong in my brain

There's really no winning as a cyclist when most people are in cars. If you stop at all stop signs, and obey they right-of-way, people will yell at you and/or try to wave you through ahead of your turn dangerously. If you do an Idaho stop (which is the safest way to approach a stop, whether it's legal or not), people will honk and yell at you and possibly try to run you off the road.

I used to commute by bike a lot during rush hour. If there was a lineup of cars waiting at a red-light, and I just waited in line, people in cars behind me would honk at me as if me preventing them from being one cars-length further ahead in line would somehow affect them. If I filtered forward, like I should, people would actually edge their cars over to try and block me.

I think for the most part, it's misplaced anger from drivers who don't want to face the fact that they are the source of danger on roads. The worst bicycle collision is way less severe than a car crash. They also really hate when bicyclists can get anywhere faster than them, which is often the case because it shows them just how much time they waste being traffic.

what's an Idaho stop?
- If you are on a bike, you treat stop signs as yields, and red lights as stop signs. Iit has been shown to be safer.
  
  If it were codified like this as law everywhere, people would accept it better. The rule breaking is what pisses a lot of people off. It would be much more predictable and safer too.
  
  Yeah, the government needs to get behind it (and tell people about it). I've come up to stop signs before, and been nearly run over from behind by cars that didn't expect me to stop.

But not the cyclist as the cycle right through it.

Classic, I'm guilty of this. The best part about cycling in my small city is squeezing into the gaps and not waiting around in the wind for the lights to cycle.
- I see it as my reward for biking instead of driving to be both a pedestrian when I want (go through red lights when traffic is clear on safe streets) and a car when I want (take a lane to get around a delivery truck)
  That and getting places faster!
  
  Congratulations, you're one of the dickheads giving cyclists a bad name.
  
  Studies show all the things I do actually make it safer for me as a biker. Example: https://www.vox.com/2014/5/9/5691098/why-cyclists-should-be-able-to-roll-through-stop-signs-and-ride
  When you are riding in and around drivers in 2 ton machines because your city doesn't have proper bike infrastructure, you take every single opportunity to avoid them. Call me a "bad cyclist" but I'm going to prioritize my safety over a law or someone's bad driving any day.

Except Berliner cyclists. They scare me.

That's not "for absolutely no reason". Some cyclists make a bad name for the rest.

Edit: Oh my goodness, you guys. I'm not saying hate for cyclists is justified, that I hate all cyclists, or that "all cyclists do x". Some cyclists ride like they have a death wish. So do some drivers. Anyone, regardless of their vehicle, who is willing to put their life in my hands is someone I want to stay far the fuck away from.

Yeah I know an A-hole driver so all drivers must be A**holes.
No some people just don't have good reason.
- You can say ass on the internet bud, it’s ok.

I think the thread was titled poorly. Anything that gets a lot of hate usually has some sort of reason, even if it may not be justifiable.
- There's absolutely no reason to hate on a cyclist when you wouldn't hate on a car polluter, because unlike car polluters, we aren't murderers.
  
  Truth. Furthermore, accidents involving a bike and a car have mostly happened because of a lack of infrastructure and options for safe travel on bikes. Public residential streets, for example, are for all modes of transportation, not just cars. Car brains are hysterical and don't like that, and my life has been threatened many times while riding my bike on residential streets. I even had an older woman match my speed, roll down her window, and say "Next time I see you I'm running you over." Cyclists do absolutely nothing to deserve this, and even if they're holding up traffic, it's no excuse for homicide.
  
  I'm sure there are many reasons to hate on a cyclist, (not that I personally believe this, but) such as when they block a single lane road slowing traffic to a crawl and placing the responsibility of possibly accidentally killing a cyclist in the motorist's hands, though you could argue that's more about the fact that the roads don't have dedicated bike lanes, and that's not the cyclist's fault, but it is still a reason, not that that reason is justified, I like cyclists!
  
  For thousands of years, people walked on roads. That's what they were for. They were also for horses, donkeys, and carts, but humans were a big part of it. And none of those four things really goes faster than a bike. Cars are new. Taking people and horses off roads is new. Being able to drive the speed limit is a new, temporary condition, and it can be taken away at any time. Blaming this on cyclists is a reaction based on a misunderstanding of what roads are for. Personally, I support legislature to let people walk on the road however they like again.
  
  That's exactly what I was trying to say. I was also a (very cautious) cyclist until my bike was stolen.
Downvoted for saying the truth. Most cyclist I met here are absolutely jerks, they drive not even on the sidelines - no, they fucking drive in the mid of the road and if you try to surpass they move to the left.
For some it’s not their fault they are a bit of a nuisance obviously (those who cycle near the sidewalks, who signal were they are going etc), the cyclist infastructure is non existent here
