4chan is the single most hostile website to me and people like me. People can't even watch porn there without first stating how much they hate black people.
I don't doubt there are interesting discussions to be had there (it is filled with nerds after all) but the userbase is very clear about who is welcome there.
Or maybe you should not take everything you read on the internet so close to heart - plenty of anons are black, Jewish and some are even women. The difference between them and you is that they have a sense of humour.
The culture of 4chan is also self-deprecating, why don't you rise up against that too and say that it's bullying against young un-successful males that can't get girls to stand within 10m distance of them?

They're also virulently antisemitic.
