It would be very surprising if you were actually hated by all men.

I mean, unless whenever you see a man you go up and punch him in the nose and say, "I am so disappointed in you!!!". That might engender universal hate. But I'm assuming you don't do that.

Since you phrased your attitude as a feeling, the question arises: do you believe this feeling is accurate? Or are your feelings perhaps doing an overeager generalization--of the same sort that might cause someone to hate all men when they only have cause to hate some?
