Before feminism, there was no mainstream concept of gender, just sex: men are male and women were female. Gender bullshit was introduced because of shit like diesel dykes who preferred tooling around on a motorcycle instead of crocheting. Men were perfectly fine with this but feminists were 100% insistent that gender is completely a social construction. Feminists were just too smoothbrained to see beyond the next step. This is 100% on them and to pretend otherwise is them lying or are absolutely ignorant of how second wave feminism led to trannies.
