Two women were talking about this boxer at a pizzeria, on the table next to mine. One was explaining to the second how she was a transgender woman and under HRT, so this was the cause of the debate. I had to step in and tell them she was completely cis and that he father didn't want her to pick up box because it was not a girly enough sport

Wtf. Days later and people haven't changed their facts yet??
- The people that spread this shit probably just quietly moved on instead of posting a correction and apology. The people that read their shit then never saw the truth.
- A lie can make it halfway across the world before the truth has had time to lace up its shoes, to paraphrase an old adage
  
  There could be a complete genetic breakdown of Khelif posted tomorrow to every news outlet that proves, conclusively, she is a cis woman, and it wouldn't matter. The lie that started everything is more interesting and has more staying power
  
  People who aren't invested in it but who hear it casually in "reputable news sources" aren't going to inform themselves on any corrections, the damage is already done

The key to talking about things you don’t know about is to be loud, aggressive, and ridiculously confident in your beliefs. Project competency though you have none.

One time in English class we had a series of debates as one of our assignments. I completely winged it and got a B+ just for sounding authoritative.
- I carry an old timey leather doctor's bag full of rusty pliers and laudanum bottles so if I ever get into a debate I can lift the bag and say "as a doctor-" before spouting off.

What about learning these phrases instead:

I believe
I seem to recall
As I understand it
It seems to me that
In my experience

In other words, make it clear to the reader what your level of skill or knowledge is.

Whilst chewing on that, consider adding a source if you have one (or six).

Source: I've been here a while and it's stood me in good stead during online (and offline) conversation over the decades.

Me: My understanding is [nuanced take on subject I do know about] but that's just what I read in [multiple good sources]
- If you're actually informed, couching your opinion like this dulls its impact for no good reason. It's good to speak/write confidently when you have cause to be confident.
  
  Hedging is great for situations where you aren't confident, but should otherwise be used sparingly.
I fully support this, and I do this too. It saves me from looking like a dickhead. Honestly I won't drop one of the "I believe" modifiers until after 10+ hours (usually 30+ hours) of not social media reading on a topic.

TRUUEEE

Even fools are thought wise if they keep silent,
 and discerning if they hold their tongues.

Skyrim is a beautiful game with no flaws heh

Skyrim is a game.

But then how am I supposed to get angry and ridicule random people on the internet?

Oh there's plenty of room for someone who is informed to get angry and rightly ridicule people who deserve it.

<group> been real quiet since this meme dropped

please make up a group. I couldn't decide on a funny one

People's whose adult children don't talk to them
- people who have literally never been quiet?
<nobody> is the only group that fits tho fr.

Point being nobody thinks they're the meme

And I'm happy she won

Well, actually the opinion on the topic you are not informed about displays your values and having it might be beneficial to you.

The problem is not in the people, the problem is in the propaganda

no investigation no right to speak
- Oh I assure you the people who you want to shut down "did their own research" and were even encouraged to do so
"Here we have completely different situation where we fucking have 2 nazi states opposing each other. Eventually, they’ll compromise leaving the world in the middle of a catastrophe"

No investigation, no right to speak, peckerwood

An example would be a parent who doesn't want any gender-related issue to be discussed in the school.

Are they inherently flawed and inherently hateful individuals? Probably not

Do they think that the schools indoctrinate children and they do care about them? Probably that's the case.
- the opinion on the topic you are not informed about displays your values and having it might be beneficial to you.
  
  And it might be detrimental to you just as easily. There's no way to know which without being informed, but an ignorant opinion based on "values" (aka vibes and what you want to be true rather than what is true) is more likely to hurt you or others in the long run. Just as being a racist bigot who has a wrong opinion about people of color might find that holding their racist opinion is immediately beneficial to themselves if they're in a similarly bigoted community, being a bigot is ultimately harmful for reasons I would hope wouldn't need to be explained.
  
  An example would be a parent who doesn't want any gender-related issue to be discussed in the school.
  
  Yet their uninformed opinion is harmful. Gender issues are inevitably part of our world and learning about them will not only prepare children to have an understanding of them that their ignorant parent lacks and help make the world safer and more livable for everyone as a result, but if that child themselves turns out to be gender stereotype non-conforming, then learning about those issues will help them better understand themselves and potentially save them from much of the misery inflicted on them by an ignorant populous.

  Are they inherently flawed and inherently hateful individuals?
  
  Yes, for the reason Dirt_Possum stayed below. They have a responsibility to properly educate themselves on issues that effect their children or decisions they may make that impact other people's children.
  
  Not wanting to explore issues like gender or race is part of why certain forms of bigotry have proven so persistent.

But she does have undescended testicles which gives her a life of testosterone. It is an advantage.

Are you joking?
- Women with XY chromosomes who have Androgen Insensitivity Syndrome (AIS) often have undescended testes rather than ovaries. These testes can produce testosterone. As a result, they develop typically female external characteristics despite having XY chromosomes and producing testosterone.
  
  In partial AIS or other intersex conditions involving XY chromosomes, the degree of androgen insensitivity can vary, leading to a range of physical characteristics.
- Female athletes with differences in sex development (DSD) and naturally higher levels of testosterone may have certain physical advantages over other female athletes due to the effects of testosterone on the body. These advantages can include:
  
  Increased Muscle Mass: Higher testosterone levels can lead to greater muscle development and strength.
  
  Improved Endurance: Testosterone can enhance red blood cell production and oxygen-carrying capacity, improving endurance and stamina.
  
  Reduced Fatigue: Higher testosterone levels can contribute to faster recovery times and reduced fatigue during and after intense physical activity.
  
  Enhanced Speed and Power: The combination of increased muscle mass, strength, and endurance can result in better performance in speed and power-based sports.
  
  These potential advantages have led to debates and regulations in sports organizations, aiming to ensure fair competition in women's sports.
