Why is hating autistic people so normalized?

I (16Q) absolutely feel alone after my best friend Davide left me. He is the nicest person ever and I feel so alone now. I go to school every day now, and every time, a group of girls will always say things like “kys, r-slur” (and I don’t mean KeepYaSwag), or “castrate yourself, r-slur*, and everyone else blames me for being sensitive, and being a man. I hate it so much, and I feel like I have to be perfect. They mock the way I walk, spit on me, and one of them beat me, but I am just alone. Everyone else at school uses the r-slur, and everyone on the internet tells me men can’t be victims of woman bullies. I am so tired of this fr
