I didn't invent the term 'sexual preference', but it obviously applies equally to a person who prefers a partner of the same sex, so get over it.
My point is that GLBT are perfectly welcome at any existing gamer con's to make themselves separate is unnecessary and smacks of 'look at me, I'm different'.
Newsflash, we're ALL different.
Fwiw, I was engaged to a bi female for months and have gays in my immediate family and gay friends and care for them all as much as the straight ones.
