Should I start avoiding men then, to protect myself from physical harm? If this is how most men talk, then I cannot trust or respect most men. 

And I dont really understand why you are saying "everyone" is like this, I certainly do not hang out around crude ppl and if a girl friend made a crude joke I would not laugh. If she continued the behavior, I would find another friend and stop hanging out with a crude influencer. What would you do?
