We’ve got a little over 50% women in the population and about 2% gays, if each gay guy has 2 dozen female friends, which would really be a pretty small number, that covers the population.
Really it’s just a normal function of population spread. Most folks have at least 100 friends of at least casual nature, about half of them will be women, and a couple will probably be gay. That’s what happens when social animals socialize, we get a large number of friends and the demographic groups that our friends are part of become rather diverse.
On a similar topic, why is it that it seems I know way more openly homosexual men than women. Are lesbians less prevalent or are they more discrete?
Knowing someone who is a homosexual is not the same as having one as a friend. I actually have a lesbian acquaintance or two, but they’re not friends in the normal sense. I had one over for Thanksgiving one time, and she’s welcome whenever. But I haven’t seen her for several years, and we never palled around. She had her circle of friends separate from me and my friends. I actually have a lesbian co-worker “friend” who is as conservative politically as anyone you could meet. But again, not a real friend (some one you associate with apart from work) but a friendly acquaintance.
