Yes, there are many stupid men. And then they bemoan their lack of loving attention. And then blame women. It is no surprise there is a whole new subculture of incels.
The really sad part is that many women would love to have a relationship with a man. I have used dating sites as far back as when they were personals ads in newspapers. I have met two wives and three girlfriends this way, all of them great women whom I loved. And it was pretty simple, just respectfully describe your non-dick qualities and say what you want. I think Plume de Poison below has it right, most of thise guys are just trolling for cheap sex
