Do you believe you have power to change how other women behave towards men? Because I as a guy, have little to no power to change what other guys believe about women or how their beliefs affect their behavior towards women.

As a guy, I pretty strongly disagree with this. I may not be able to change their beliefs, but by actively calling out their behavior, I can sure as heck change their behavior. When people know that saying something awful or treating someone poorly is going to make for a really awkward conversation at best, and possibly lead to being socially ostracized, they tend not to do those things.

Maybe you are particularly persuasive, but the guys I have known who harassed women would not take anyone seriously if they were told they are being inappropriate. They may stop in that moment but will go right back to it the next day. Based on my own experiences, men who are fairly conscientious to begin with and listen when someone tells them they are being jerk are generally not the problem.
