Even though i'm gay i don't think i would join a LGBT guild
This is my fourth MMO i'm playing and i've never hidden my sexuality, even guildies flirt with me (ofc words only) but some remarks they make are really funny :-).
I don't know about US, but Europe seems to be more tolerant. Although i always joined a +25 guild. Or maybe i've been lucky.
But i say, Anger, ignorance and all negative things leads to the dark side
