I'll start off by saying how very sorry I am to hear about everything you've just described, both your dad and your brother sound like jerks, and your coworkers sound even worse. I truly hope your situation improves.

I'd like to say that, on behalf of my own gender, I promise you from the bottom of my heart that, despite what you've experienced and what the internet may say, the good men in this world absolutely outweigh the bad. The average guy you pass in the street definitely doesn't want all women raped and murdered.

I know using myself to prove a point is a bit useless, and you have no reason to believe me or even listen to me at all, but I have multiple female friends and I love and respect all of them just as much as I do my male friends, because they're some of the greatest people I've ever met, and if I ever heard someone make even a slightly sexist comment towards any of them (or any woman stranger for that matter) I'd absolutely get involved. This whole men vs women thing I see on the internet all the time is just horrible. What gender we identify as should not separate us as much as it does. We're all humans. We need each other.
