I'm amazed at how many here are jumping to the conclusion that the guy probably is gay. To be honest I find this to be insulting to Angela, and to transwomen in general.
If anyone took the time to look at some of the previous posts that Angela has made, she has been told often that she is passable. She has said that this has been said to her from her wife and from friends. So if she is passable, then why would a gay man hit on her? It seems to me that a gay man is looking for a man, not a woman. To me, if you are assuming that he is gay and hitting on her says that you think Angela is coming across as a man, not as a woman. Insulting don't you think?
Maybe he's just a friendly person that enjoys interacting with other people. If he is hitting on her, what difference does it make if he is gay, bi, straight, or even a chaser. Why can't we just accept that someone found Angela attractive/interesting and leave it at that? Why are we so quick to label someone that we have never met?
