Pretty sure this is a bubble view point, look at how many right wing populists are successful in the world right now. Conservatives are not a small group and I'm sure their views are considered good and normal in many spaces.
But it's easy to say "it's the corrupt society that is wrong" or that social media is full of bots or commies etc, it can serve to validate their views. Like the hero in a dystopian story, they are one of the few that see the truth.
It's valid, what you said. But the internet can also be a huuuuge asshole. I'm not excusing the awfulness that is conservativism (fucking ew furiously washes hands) by any measure; self-reflection is a requirement of a sentient human and is absent in some animals. However, one does see how an opinion from an asshole so very vast might get discounted, folded-in with the cheese of selection bias, as it were.
