Sweetie, don't take what I'm about to say the wrong way, but I'm going to be real with you:
You need to value yourself a little more.
I'm only saying it because I've been there before, I have friends going through it right now, and I see it in you. I know exactly what you're doing: you're looking at these douchebag profiles and taking them in as a loss for you. You're looking at these profiles with their fucking racist 'No fatties/blacks/asians/dark-skinned hispanics! Sorry, just my preference!" and you're thinking to yourself, *sigh*...if only I weren't black...If only I weren't this/that/the-other-thing this person would talk to me, and we'd fall in love, and we'd be happy. But I'm not what this person wants, so I'm unhappy...
You can't let your self-worth be so tied up in the opinions of people who aren't you. Especially not some racist-ass anonymous profiles on gay dating sites. I don't even have to know you to know you're worth a LOT more than that. Always know that.
Instead of looking at these dudes as a loss, you need to have confidence in yourself, what you have to offer, and look at these dudes as loudly advertising how worthless they are and why they were never worth your time in the first goddamn place.
I mean, do you want to date a racist? Do you want to be that experiment black dude that the racist tries out for size? I can tell you right now, it's a waste of time.
