Consider this. 62% of the British female population is overweight/obese, higher among Americans. Previously every single land whale you see in day to day life would have been of average size 50 years ago.
Perhaps this is the reason for the increased simpification of dating; the astronomically smaller pool of average women results in a completely disproportionate amount of attention being lavished upon women who are average at best. (But due to not being fat are now "hot".)
This would also increase the difficulty in online dating for men tremendously, because the pool of acceptable women for all men has gone down dramatically and thus simultaneously increased the relative price women can command in the SMP. Some men are going to praise ugly fat women like her, unfortunately.
