Masculism is a great recruiting tool for feminism. Everyone is best at seeing the problems that affect them personally. A man skeptical of the harm caused by sexual harassment or the beauty myth may be well aware of the harm caused by macho attitudes toward sports injuries or the social pressure to be “a success.” If we have a gender egalitarian movement that addresses his concerns—not in opposition to, but along with, women’s concerns—then we have a movement that has massively expanded its potential base of supporters.
Many men get a bad first impression of feminism from zealous young feminists who, regardless of their intentions, alienate the heck out of men. Some of those men will later see the nuance that they initially missed and come to understand the value of feminist thinking. Many, perhaps most, will not. This is not a net win for feminism. Most feminist spaces, online and in the real world, are not particularly welcoming to men. Even given that there are often good reasons for that, how many men have been lost to gender egalitarianism forever because they didn’t put in the extra effort to overcome that perceived hostility, or because they had already had their bad first impressions cemented and were not willing to change their minds? What might have been accomplished by not chasing away so many potential allies?
