Arab men hate transgenders but they have one thing in common They both wear dresses
What kind of assumption are you making about Arab men? Why would you think this?
Arabs are homophobic and transphobic. They refuse to accept people who are different from them, that's maybe the reason why some of them wear dresses...
Making stereotypical jokes about all Arab men is not right.  Every culture has their own ways of dressing, and will look strange to other cultures.  How would you feel if you were made fun of based on your style of clothing?
