Regardless of the real quantity, society will blame all sexless men for their lack of sex because to acknowledge any other reality would mean that something is wrong with how we are dating.
Isn't it easier to hide these things on a Tinder profile than in a nightclub?
Furthermore, I think that these apps mostly reflect reality. In the offline world fat people would have a hard time finding dates too. Don't you think?
Most of the problems with online social networks and dating apps are not brand new, just a lot more severe.
The apps simply reflect peoples' superficial preferences. It's way easier to swipe left on a photo of a fat guy than it is to reject a fat guy who you find attractive because he is kind and makes you laugh. Personality really is most of it, but personality doesn't come through in apps.
