Ladies' night

We at WWPD are familiar with the arguments against straight women going to gay bars. These, however, assume that the bars in question are for gay men. Jezebel has now reposted what I think is a rant about straight women popping up at lesbian bars.

This I'm having trouble wrapping my head around. Is this a thing? Groups of straight women, unaccompanied by lesbian or bisexual female friends, just showing up at lesbian bars/lesbian nights at gay bars? Not because they happened upon the establishment - and who among us hasn't, in our more social youth, ended up at a bar geared to a sexual orientation or gender not our own, because it was a bar and it was there, not cared once we noticed if we even did, had a drink or two, and moved along - but because they sought this out? Isn't the idea with gay bars that women believe they can escape being hit on? Wouldn't a bar where everyone likes women (as vs. a straight bar, where maybe half do and half don't) defeat the purpose? Isn't it more likely that a gaggle of girly-girls who've sought out a bar for gay women are gay women, but just femme gay women, or - if ill-at-ease - semi-closeted/newly-out?
