I’m not sure if you’re being intentionally obtuse, the point was “Let’s not use ‘feminism’ to reinforce gender roles and gender essentialism.” I’m a fan of the postmodern type feminists (think Jodi Dean) and not so much of SJWs because of exactly this problem.
Look at the link (Or contemplate it’s unstated examples of people like Radia Perlman and Limor Fried) : Women get respect in many traditionally male dominated spaces when they recognize the (usually sex independent, though sometimes gender encoding) norms of the space instead of expecting it to conform to their conditioned gender role. Look at the outliers to either end for degrees issued in various fields by gender. The narrative is that men don’t tend to go into nursing or teaching because of socialization and social perception, and women don’t go into CS or engineering because the professional culture is poisonous to women, but we’re really talking about exactly the same phenomenon in both cases.
I don’t see “Sewing is Over” headlines because the culture around that is historically female dominated and thus some of the encoded values in the subculture are unfamiliar or uncomfortable for folks with traditional western male socialization (and I say this as a dude who enjoys sewing). We all [should?] have multiple personas that we project to suit the subculture we’re interacting with, I project differently depending on which hobby subculture I’m currently in with (and, in a self-aware way, probably harm my long-term career prospects by not projecting differently in Engineer and Educator roles) because I respect the subcultures and their role as a comfortable space for the people who constructed them more than I want everything to be tailored to suit me.
