Harassing others based on their loveual orientation is not a political belief, it is a personal belief, it is prejudice, in the same way that racism is not a political belief. If someone is harassing you for being a straight white male in school then I'm absolutely certain they would get the same treatment.
It very well may be a political opinion. A political belief IS a personal belief. There is no evidence that they actually harassed them for being "x", they were probably just doing it to be "funny". Even then, it is not the school's place to change those. The school is supposed to be totally neutral.
this is what you need to explain.
I think Kishgal said it well. They are, in a way, "attention whoring". I think the Key and Peele skit displayed it best. Being gay does not make you any more special than someone who is not gay, so there is no need to act like it, and then label anyone who calls you out on it as a "family man". Do you understand what I'm trying to say? It's really as simple as that.
definitely gonna need some sources on that one
This is not entirely false, but more of just me giving you stuff for being a feminist. Sorry that you weren't able to get that.
