I'm not white, to save you making further "presumptions". Your suggestion that white women weren't solely of the oppressed class is crass, frankly.
There has never been a time in history where women, all women, were not disadvantaged to a greater or lesser extent solely because they were women. Not at any point in the past, and not today. Yes, there will have been privileged women who facilitated, to some degree, the oppression of other groups. Did that mean that they had equality with men? Did they have total autonomy over their finances, possessions, or even their own bodies? Did they have equal financial and legal status to their husbands, brothers and fathers? No, no and no.
Wherever you have an oppressor class you have an oppressed class - even if that oppressed class plays some role in oppressing a third group of people. Where that oppressor class chooses mockery of the oppressed as a form of entertainment, you have a problem. Your objection to the use of "womanface" as equivalent to "blackface" seems to be an attempt to ring-fence racial oppression as some kind of "worst" in a hierarchy of horror. It's not as simple as that, and all the creation of a hierarchy achieves is to prevent oppressed peoples uniting in the drive for social justice and equitable treatment. It only benefits the oppressor.
Maybe stop and think and foactual understanding of why you are so intent on playing Oppression Top Trumps that you are willing to negate centuries of misogyny and patriarchal mistreatment.
