Must I have to break away from some of my friends?
Why do you want to break away from your friends?
I feel disgusted with them because of the way they treat the opposite sex as objects
Sometimes friends grow apart and their ideologies change. Friends deserve to let each other know they're no longer interested in hanging out though so be straight forward with them when moving on. If not they may try to keep hanging out with you and that'll make things awkward.
Tell me what to do and I'll do it.
Certainly, I believe you can first try to convince them that misogyny is wrong, and that women don't deserve to be constantly put down. If they just shrug it off, why not just finally leave and find more worthy and kinder people? I don't think those kinds of people need to surround you!
