It's sincere.
I just have legit and honest doubts about how much can really be achieved that would truly end the atracks on women and women's spaces so long as the primary or most significant of defining oneself as a man is in comparison to women and specifically by othering women and labelling "feminine" qualities and characteristics as "bad".
As long as that's the case, seems like men are always going to tend toward abusing women and 'improperly functioning males' as a means to restore their manhood whenever they get self conscious or 'lose' a challenge, or what have you.
The violence won't end just by restoring male/male relationships.
After all, the Spartans very much valued male brotherhood and Spartan women had more rights and better lives than most Greeks.
There was still violence against women in Spartan society. So much so, that women were granted a dagger to mark an abusive man. Getting that cut could lead to ostracization or even exile, but the fact that the dagger was given out to almost all women suggests that it wasn't that rare and occurance.
Still. I wish you luck. We're not Sparta, so maybe y'all will get it figured out. It won't likely happen in time to affect my life, but I have a daughter and I may have grandchildren some day.
Why would you think I wouldn't want better for them? Regardless of how I may feel about men today, I'm not so petty that I wouldn't hope for better for our progeny just to be spiteful toward men.
