This doesn't seem to be a case of a good man being dragged down by an angry mob. This is a well known jerk being shown the door.
If you are a phisically attractive man, women WILL make advances at you and try to have sex with you. I don't know about the U.S., but here in Europe and in Canada it certainly is the case.
Try to think of men and women as exactly the same, just with different genitals and bodies. This might be an oversimplification, but it is nearer to the truth then our common preconceptions about men and women. Before I got to that conclusion I used to have only male friends and I didn't get along well with women. Now my closest friends are women.
If you seriously believe this "natural relationship" stuff, you might be part of the problem. Also, you're restricting yourself to a certain kind of relationship to women and you're probably missing out on some great experiences, including sexual encounters.
When women start asking men out at a similar rate as men, then maybe there isnt a "natural relationship" anymore. A large preponderance of data from places like Tinder, OK Cupid, etc completely contradict you in a very statistically signifiant way. Call it cultural all you want. I'm just going to call it common sense.
To me, it seems to be "harassment" if the female isn't interested, but that can be a very fine line between the natural relationship between men and women that almost always requires the man to make an advancement and put himself out there.
