You're not alone. This short non-white guy has also found Tinder abysmal and self-esteem thrashing, with only a couple matches after hundreds upon hundreds of swipes. (Unlike your comment, I won't dismiss those matches as unattractive, which would be unfair, but the fact that the very few matches I have gotten have been the same color as me suggests to a paranoid mind more than just coincidence regarding all the other rejections...).

Like you, I've had much better luck with OkCupid, which makes it distressing that the online dating population in general seems to be shifting from OkCupid type sites to Tinder type ones.
