So, I am a kid. Specifically, I have a condition where I stopped developing, making me a kid forever. For that reason, it always makes me very uncomfortable when people talk about how much they hate kids, even though they're usually referring to ones half my age or younger.
It's fine to not want to have kids. I wouldn't want them if I were able to have them. But I feel like outright hating is going a bit far. I wouldn't say it's on the same level as racism, sexism, homophobia, etc. because people who hate kids ~95% of the time don't harass or attack them, they just avoid them as much as they can, which is pretty much what some introverts do with people in general. But they still hate a group of people for something they have no control over and make generalizations about that group.
For parenthood, I've always thought there should be tests to determine whether people should be able to parent. Here are some people who I think shouldn't be able to:
-alcoholics or people who have some other kind of major addiction that gets in the way of daily functioning
-people who have a history of anger issues/outbursts (MAYBE they can be considered eligible if they haven't had any recent ones and there's reason to believe they've changed)
-people who wouldn't accept their children if they were LGBT+ (it's fine if they would still love them despite not approving, I'm talking ones who would for example beat their kids, throw them out on the streets, or make them go through some kind of "conversion" exercise)
