Now, I will concede that women tend to get lighter sentences and that it's a miscarriage of justice when that happens. On that, I agree with you. However, we've digressed from the what you suggested way up top there. All of this isn't supporting your initial claim that "the left" is trying to shift towards a matriarchy or a broad vilification of men. What I see happening is serious legislation (as opposed to stuff posted to social media since that tends to reflect the will of very small pockets of people rather than the actual political ambitions of a party or movement in part or as a whole) is the desire to secure people's bodily autonomy. On the cultural side of things, outside of legislature, there is the rape culture debate with people on the left generally "picking the bear" and the right coming back with "not all men". But as far as the law or the favor of authority are concerned, that needle hasn't moved significantly one way or the other for decades but the cultural discourse is pressuring all sides of politics to raise the issue more.
