I've noticed the female equivalent of this strange sort of self degrading lefty virtue signaling is when women who normally complain about "creepy" guys hitting on them declare that they would perform all sorts of involved sexual acts on and with the person or persons (usually an older male like "bernie" that would, in any other context be categorized as 'creepy') that align(s) with them politically/ideologically....It's like the world has been waiting in the wings for these idiots to degrade themselves and this is the price for the degradation....
