This is a great point. If a small percentage of the population is openly and aggressively negative towards another part of the population, it makes sense that they would both artificially appear as if they are a larger part of the population, to each other. I think it goes both ways.

Anyone who's a bit different has a high chance of having been bullied at some point. It doesn't mean that society hates this specific group of people.

I _highly_ doubt 90% of nerdy people were tormented during childhood. Have you spent time in/around academia? These people are massive nerds and horrendous childhood torment is pretty rare.
