I think people who watch anime are gross
Do you think you're better than people that watch anime?
Yes. I've watched anime before, but I've grown out of it and become an adult.
It sounds like you have judged a situation without knowing the whole story and just because you don't like anime any longer doesn't mean that it's gross.
Yes it does. Anime is gross and I was dumb when I used to watch it and anyone who still watches it is dumb.
Perhaps you just had a bad personal experience with anime. I'm not an expert, but isn't anime just some cartoons? Instead of focusing your anger on people who like anime, perhaps try to focus on something that you personally enjoy.
