Is it just me or tall women are often alone and dateless?

Whenever I go to the mall or in any other crowded place I see tall women (5'11 or more) often alone and unaccompanied and I'm talking of week ends where you would expect to see them with their partner. Is it because their physical hypergamy prevents them to pair up with men shorter or not enough taller than them? Or is it because men stay away from tall women? Personally I wouldn't mind a girlfriend taller than me, it might have to do with my femdom fantasies and I imagine there are quite a few other guys like me as the popularity of femdom might suggest. I was even considering the possibility of day-gaming one of them even though day-game is quite uncommon and many female users in this very same sub commented how annoying is going through your day and being hit on by random strangers.
