The equivalent would be to enslave white children to show them what slavery is.
Seriously, why do you think it’s okay to discriminate against people as retaliation? How do you think that helps anyone? Do you really think, a misogynist will stand in front of this art gallery and reflect whether women might actually be real humans after all? What’s happening is, that a bunch of selfrighteous pseudo-intellectuals will jerk each other off on how progressive and artsy they are, and a bunch of actual misogynists have even more fuel for their crowd to stoke their hate. Wow. What a win for everyone involved. Alienation of former allies and even more hate. A true victory.
But it’s not good publicity, just like the soup throwing is not food publicity.
Everyone already knows about both problems and everyone who wants to have an opinion already has one. But those who are on the fence about it, will be alienated by this.
Such an action might have been a reasonable publicity stunt in the 20s, but definitely not today.
