It is good to see the number of posters who support GLBTQ's in their organizations.
The only thing I will say is the best thing is to get to the point where if someone asks the questions if you allow Gays in your org, you are able to look or type with an incredulous expression--"a that's a silly question, or course we do" answer and leave it at that. When you start giving examples it starts sounding as if are trying to convince yourself--sorta like the "are you racist" question that people answer with "no I am not, my next door neighbors are Black and they have been to my home".
