From what I've observed, a lot of them are definitely straight but call themselves "queer". I've said it before and I'll keep saying it but I haven't met much of any fellow gays or lesbians who call themselves "queer", it's usually bisexual and/or straight women who do this and of course they would, they aren't completely same sex attracted so they won't fully understand why many gays and lesbians don't use that word to describe ourselves.
