These gender ideologies and the application of positive discrimination are an affront to left position. Since more than a hundred years, the left strongest identification trait was the fight to end discrimination. When now discrimination is applied in the name of diversity, that can't be a left value. This is something else, and it comes from somewhere else.
I'm not saying the position does not exist, and I'm not saying the groups purporting them don't look like left groups. But talk with some communists or socialists. They can't get behind this. My point is that this gender movement is its own political/ideological thing, that has just a very small overlap with left identification markers. It uses their style, not more.
This is probably part of the usual problem, that the left-right distinction doesn't really capture the political landscape.
