No. I like diversity and wouldn't feel too comfortable in a place like that.
I think Sarah Louise's comment is very true about there being no utopia. Being that I'm a tree hugging hippie, I once really believed (or wanted to believe) that humans could create a loving uptopia if we all came together and tried to find common ground. However, there really is no such thing as a place free of conflict or problems as much as I'd love to believe in it. What looks like a paradise to one person can be a nightmare for another. A trans community would still have plenty of issues and struggles to overcome even if it did solve the transphobia problem. I'd much rather have an inclusive and diverse society that can learn to integrate the trans community into it. And judging by the way history is turning, it's slowly becoming a reality. Excluding ourselves seems like a step backwards in my opinion.
Having said that, I wouldn't mind a trans version of San fran or something. A place that is transfriendly but not exclusionary.
