I have an autistic teenage brother whose hobbies include watching football, watching series, and spending a lot, lot of time online. He is very studious and gets good grades, but he is also very introverted. I've never seen him show much interest in girls or in dating/sex, I even asked him once if he was gay and said I would support him regardless of what he liked, but he got annoyed with me and said he would never date any man or woman, so I don't think that's the case. Recently, I've seen him saying strange things with a lot of hate directed at women, especially single mothers, women who cheat and extremely religious women, in addition to using weird internet slang sometimes. He even says very offensive things, like calling them whores and saying they are gold-diggers, and when I complain to him, he simply says he 'isn't talking about all women, only the ones who deserve it.' I think it is important to highlight that he does not show prejudice toward other minorities. My father doesn't care about this. What should I do?
