I think this is steretyping to be honest. To say that it is mainly men and you avoid airlines that only employ men or mainly men. I think this is sexist and in my honest opinion, as a guy myself, offensive!
I am not saying there are no people like this working as crew, but what I would say is they are most certainly in the minority! I am sorry you got this treatment, but you should have reported them. This kind of behaviour would not be tolerated.
There are strange people in all walks of life and they are men AND women. They are in the minority though so I don't think it is particularly healthy to hate on a certain group of people, employees, or a certain sex though.
