So here's the question - is the scale consistent over time? That is, do we consider the same ideas left/right wing in 202x as we did in 199x?
Let's assume it is. We're seeing men lean towards the center/right, and a lot of people are asking why. The trouble is, the answer isn't one people like to hear - in our headlong pursuit of equity, we're introducing a lot of inequality. You lift the ladies up, while you let the men climb - all based on the assumption that the women had further to climb so what you're doing is levelling the field.
Countering this is a sympathetic voice, one offering to bring back equality or offer a different kind of equity. Casting gender equity as a zero sum game, and pushing for equality aimed at the ones not being lifted up.
I often hear the "uneducated men" argument, but that's just an ugly echo from the past serving those it once oppressed in a bitter irony. The reality is that even educated people can fall for propaganda. Especially when voting in what they see as their own self interest.
