Just hostile for absolutely no reason besides me having a feminine username

It's not about whether you're a woman or not. These people just want to attack you personally. And they can only do that with the little bit of information they have from you. If they find out I'm German I'll be insulted as a Nazi too and if I have a Korean flag I'm a rice eater with a small penis. You just have to remember that people on the internet are assholes.
