It seems to me that there are two basic kinds of tranny support organizations; the rocket and the valve.
The valve assumes tranny support as a kind of escape valve, a place to go and let off steam, release the pressure so you can go back to normal the next morning.
The rocket assumes that tranny support as a kind of booster, a place to go and become empowered, build the pressure so you can keep going and effecting change in your life and in the world.
The valve is for those who seek to maintain the status quo, while the booster is for those who want to become new.
Maybe all organizations have to include part of both, but the balance is what makes the difference.
Me?
I like to be balanced towards the booster.
