I really feel like this is an idea that needs to die. Plenty of abusive and hateful men seem to have no problems with getting the type of relationships they want; this just inadvertently promotes the idea that one needs to be a ‘nice guy’ in order to have a relationship. Not every guy who leans left succeeds in wooing a woman, and right wingers complaining about where the women are at are probably in circles with primarily left-leaning women and they need to go look in a church or country concert or something.
