The problem is not that you can't find someone who is x, the problem is that when you find someone who you want to be with, and you don't give a flying fuck if they are x or non-x, you still get your relationship ruined by other x being dicks to your non-x and to you by extension. That is the problem. And no, those sites do not solve it, if anything they might make it worse. (You should dump your non-x because look how many eligible x there are on xdate.com and xpeoplemeet.com)
