I will say from past experience that some people don't like to be messed with. When I was 22, some friends and I were in a small little hole-in-the-wall bar and some guy started harassing two transgender girls for "messing" with him. I'm pretty sure he was the one flirting with them and then he realized they were transgender. (side note, I was being a long-haired boy that day) One of my awesome hippy friends - I used to call her big mama Sarah - kicked him out of the bar. She didn't work there either, she just kicked him out.
The moral of the story is don't put yourself in a bad position and be safe. Also, you me and everyone thats TG is an ambassador for the TG community. It kind of sucks but its also kind of neat.
