Teenagers have no empathy

I say this because at least in my school, anyone who is even the slightest bit different gets made fun of and bullied. People tell people to suicide and self harm and defend themselves by saying it's "dark humour" which it isn't. They also are some of the most homophobic, racist and ableist people I have ever seen. If you get in any sort of bad or unfortunate situation, they make fun of you. It feels rediculous that teens have literally 0 empathy and ruthlessly make fun of anyone even slightly different. I despise them and am baffled by how little empathy they have, I'm saying this as a teen myself.
