I'm not going to call you a bigot, as DracTarashV2 has done. From my few encounters with you on these boards, you strike me as sincere and fundamentally decent.
However, what I will say is that, irrespective of the unnecessary personal insults, DracTarashV2 has a point.
'Whiteface' is hardly a problematic historical phenomenon on par with 'blackface'. 'Blackface' and minstrel performances, some of which were performed by African-Americans darkened up even further to play grotesque caricatures of their race, for the amusement of predominantly white audiences, has a shameful and disturbing history. In many instances, black performers were barred from various events and displays, including the Miss America beauty pageant, except as a 'comic' troupe of minstrels, occasionally wearing fake chains in order to simulate slavery. And in practically all cases, blackface was intended to demean black people, robbing of them of their agency, and upholding repugnant racial fallacies that held black people to be 'less intelligent'.
Unlike 'whiteface', 'blackface' is a case of punching down. It's people with relative power keeping black people in 'their place'. By contrast, super-rich white women may still experience sexism, as all women do, but, by-and-large, they still belong to a relatively privileged demographic, and for the most part these women were being mocked not for their gender per se, but for being particularly spoiled and over-privileged examples of white womanhood.
