Post right here and ask away. Admittedly, there will be a few who may be offended by the course of questioning, and I understand that. At the same token, I would much rather have someone ask questions, no matter how invasive, in the hopes that you learn a bit more. How else is anyone to learn without asking?
I'll be the first in line to support a straight individual who seeks more information about the g/l/b/t community, even if their line of questioning may be construed as potentially offensive. I'd rather they ask, than simply make assumptions which likely aren't true.
Folks, how can anyone hope to gain insight (that we hope for) without first bringing up the topic at hand. I'd much rather have someone ask "What do I tell my children if they see two men holding hands?" as opposed to "I don't want my children to see two men holding hands because I don't know what to say."
