That's something I have argued about with my liberal friends often. You don't make allies by telling people that their opinions don't matter, or that they're wrong based purely on their sex or color. The left has been dismissive towards men, no... It has been hostile towards men for at least a decade. Masculinity isn't inherently negative and not all masculinity is toxic. Spreading the belief that it is will only make enemies of people who otherwise would be allies. It is incredibly short sighted to reject normative people and make them feel that they're less important or that there's something wrong with them just based off their birth. Also, that is the exact same mentality that the left supposedly wants to overcome, but rather than working towards its end, they've just shifted the target. To be clear, I say "liberal" and "left" and that may cause an assumption that I'm a right-wing conservative. I am not.
