This is a question that I always turn around on.
My question to you is,
"What's wrong with dating a gay or bi man?"
the only criteria you should really be looking for is "Does this person accept me for who I am?"
Instead it's usually "I must find the most macho hetero man to prove to the world that I'm a woman"
Lets face it. Transgendered people go on and on about acceptance and yet when someone finds them attractive and alluring your suddenly a "gay tranny chaser."
I amuses me that a group of people who demand acceptance and preach tolerance are usually so willing to buy into the whole "Only two genders" line and have very conservative outlooks when it comes to selecting partners.
