Why tomboys are always so rude and offensive than girly girls?
I am not talking about girls who just dress like casually boyish type but in general tomboy girls personality types.
They are always rude and offensive, treat almost everyone badly, follow men, and tend to have more male friends but they inherit only bad personalities from men and not a single good one.
Most men are not rude and offensive to talk to. I will never date or be friends with a tomboyish girl personality-wise. I don't mind if she's low maintenance and isn't more into fashion.
