There is also movements in tech (that we all most likely are aware of) to promote SJ and women in it even when the women them selves don't want it.
When I was taking programming classes in the late 00s/early 10s the professors would give special attention to the women in the classes even if they didn't want it. The only reason why the guys in the class even made an effort to talk to one of the girls in one of the classes I had, was because she worked for Micro Center.
