A lot of people are a little weird. The question is, are they a little weird in a good way? ;-)
I've never felt threatened or bothered by anyone on account of her being lesbian (or bisexual)...although thinking back...I have known one or two lesbians in the past who were just plain obnoxious, but it wasn't because they were lesbian, it was just because they were obnoxious individuals, period. ;-D
