I think you underestimate the sheer number of homophobic parents that aren't necessarily abusive but would be if their kid ever came out. There are a lot of people I've talked to that their online escape was the one thing that kept from killing themselves.
I'm not saying that it's healthy but there are a lot of kids in a situation that they can not escape from because of the way that society treats children. Children are treated as something that is closer to property than an individual when it comes to things like law enforcement and emotional abuse.
Actually I don't have to be ok with anyone contributing to the burning down of the planet. I feel like adults should have a better understanding of morality than simply "its against the rules and is therefore wrong".
