It depends on what your intentions are. If they are for meeting trans people, no, I cant see them letting you attend. If you are the SO to a trans person, yes, more than likely they would. Support groups are for education, support and advice and not a pick up place. A lot of trans people are wounded emotionally, physically and spiritually most of the time. They need to be comfortable in meetings and not be scrutinized or asked out. 🙂
