There are nearly twice as many gay-identified men out there as there are lesbian-identified women. This fact alone is all the proof we need that homosexuality isn't a choice. Considering what shits straight men can be - judging from my mail - surely more women would choose homosexuality if they could.
Anyway, it seems to me that what single lesbians need - in addition to dyke bars, Internet personal ads, women's softball leagues and cat-food aisles in grocery stores (man, those lesbian/cat jokes never get tired) - is a secret sign. I'm thinking something subtle, SMY's, not because I''m pro-closet, but because I'm pro-tasteful. Message T-shirts? Never tasteful. And "Nobody Know My Girlfriend Is a Lesbian" T-shirts are very 1995 (and highly unlikey to get a single girl a date).
Instead, maybe all lesbians everywhere should start wearing a button. No words, just a solid color, something small and tasteful that could be pinned to the strap of a purse (popular with "not-stereotypical-looking" lesbians), the lapel of a jacket or the belt look on a pair of jeans. Thinking outisde the lavender/pink/purple box, I think the button should be green - green for "go", green as in "Go ahead and hit on me, ladies. I'm a lesbian."
