I think I'd be hesitant (in my heart and mind) to go out with a Middle Eastern man because I'd be afraid he'd be too overbearing toward me and subjugate me to him and other men because I am a woman.
Maybe it's a stereotype I have that he'd make me stay home and wear a burkha or something...but honestly...that's what I'd be afraid of.
I'd be a little afraid of the male superiority complex and how it would affect me.
Are you so passive that you'd get involved with a very overbearing or controlling man, and then continue to stay in a relationship where you were overly dominated or made to feel inferior--no matter what the ethnic or religious background of the man was? Why would you be so hesitant to go out with a Middle Eastern man? Wouldn't it be like going out with anyone else? If you didn't like the way he treated you, or what he demanded of you, you could just stop seeing him.
I don't think you are racist, but I think you are stereotyping Middle Eastern men, and your fears about them seem based on your feeling that you would become a doormat in that type of stereotypical relationship you envision. That's really saying more about you than about Middle Eastern men. Middle Eastern men don't all think alike. They don't all treat women alike.
People can have preferences, or aversions, toward people of varying groups for all sorts of reasons, both logical and illogical. When I was younger, I went through a phase where I had a preference for all men who weren't American. Any sort of accent was a real turn-on for me. The non-American men seemed more worldly, more sophisticated, more knowing of women, more polite, more romantic, more everything. Then, after a while, I realized this was mostly going on in my own head, and it was more a matter of the individual man rather than anything about his being a member of a particular group of any kind.
Groups are comprised of individuals, and it's the individuals we get involved with. Personality and temperament and intelligence can easily outweigh factors of ethnicity or race when it comes to who we find attractive or who we dislike.
