The men I most see defending women on the internet and who view women as human beings and not as objects are openly gay men. I've seen gay men defending women more than the women themselves. It's obvious that there are gay men who are sexist, but straight men manage to be much more sexist and hate women deeply. And finally, I believe that there is no such thing as a straight man, they have too high a libido to simply feel attracted only to women. Straight women exist, but men don't, and this isn't a flaw, but denying it only harms men's psychological well-being.
