I find it's also helpful to look at such "taglines" for what they are, generalizations. It just so happens that when we generalize about women it's sexist, when we generalize about races it's racist, and when we generalize about men it's "just a tagline." I know men aren't supposed to admit we have feelings or else we're weak, but we do. I've been cheated on 3 times and raped twice, all 5 were by different women, does that give me licence to ~~generalize~~ "create taglines" like "Women are trash?" Hell, I can't even use the word "female" to the degree where I sometimes write "males... and women..." instead, lest I be crucified as a pariah, but if I call out "Men are trash," literally, I'm still seen as in the wrong.

No. Something's gotta give, can't have it both ways. Either women's "taglines" are bad too or men can also generalize about women. Personally I lean towards "generalizations are stupid, tagline or not, and basically by using them you hurt yourself (your movement) in your confusion like a goddamn magikarp."
