I don't care about how early people get up each day and the many things they got accomplished because they put off sleeping because they think, wrongly, that sleeping in means you're a lazy slob.
I don't care about if other people my age aren't married and have kids, why should they care about me?
I really don't care about your skin color, your sexual identity, or your gender identity. You're all human beings. And I sort of, kind of hate humans. 
I don't care about great your sex life is or how many people you've slept with. Well, actually I do care, I find it disgusting and creepy when people brag about the number of people they've slept with.
I don't care if you're still a virgin, but I do care about how people think someone, especially guys who haven't lost it while still their teens are complete losers, incels, or come from a strict religious background. It's just stupid.
I don't care about words that get censored because they might "trigger" some people like "suicide" or "murder" in YouTube videos that are clearly not meant for children. But do they swear a lot and get away with it all the time, which I do hate. It's like people can't say a complete sentence without dropping the f-bomb, and if you complain they think you're a loser. It might be a sign that I'm getting old, but I've felt that way ever since I was a kid and it got especially bad when I became a teenager, of all things.
