OldGuy raised an excellent point. I'm black and it baffles me when other black people marginalize gays. Were we not fighting the same fight roughly 40-50 years ago? My marriage would have been illegal less than a half a century ago. How can I NOT identify with their struggle?
Getting off track. Anyway, just because you've felt judged at one point doesn't mean you should pass those bad feelings along. And I think if people struggle with the realization that they're poly, when they finally get there they find a sense of relief and elation and want to pass that along.
