I am in the middle on this one. There are a lot of negative stereotypes out there but there are also some great ones as well. I don't mind someone poking a little fun. When asked why I am who I am I attribute it to drinking diet soda from a plastic bottle and watching too much Monty Python.
I agree with Megan. Its easy to draw stereotypes about a minority that you have had no association with other than what you see on TV or the internet. The two best ways to overcome those sterotypes is to be proud of who you are and to conduct yourself like a person that someone would want to associate with.
I have have had some wonderful experiences with folks that have never met a transgender person before. I prefer to blend in, but if noticed I don't shy away from who I am and I certainly don't worry about what the other person watched on TV last night.
