What is purpose for this post? Are looking for support or opinions on the if is a good idea? i believe any action to support freedom of a gender fluid society is the a positive as joining LGBT organizations is.
Every LGBT center will offer something different. I attend a support group for married (to women)men. There are lots of other groups run by the center, all of them appear to be helpful to the people who attend. So I would suggest that you might find your local group helpful. If you need support or just want to hang with other LGBT people your local community/ center is a good place to go.
I joined the LGBTQ center here. It helped me feel like I am a part of the community. I go to some activities, and a men’s group. Joining made things seem a little more real about my limited coming out.
