There's no reason to be friends with everyone. Schools teach us to respect others, but how often does that respect actually come around?
We've all met really shitty people - both men and women. Society, especially school and college, tells us that we should be friendly and courteous towards others. Yet again and again, guys come to TRP and lament about how awful they are being treated and how unfair the world is. Regardless of how kind or considerate we are, that doesn't matter. A lot of people out there are trying to screw you over in one way or another.
Stop trying to be friends with everyone. If someone is an asshat, or if some woman is a bitch, stop interacting with them. Block them off on social media (FB, snapchat, etc.). Use that blocking liberally. You don't need to "stay connected" with their life. Your Facebook account doesn't have to be filled with literally everyone you have met once or barely know. Adopt the abundance mentality. There's better people out there and you don't need to fake being friends with shitheads.
