tbh lots of unions got pretty diverted yeah.
In my view, intersectionality just means that all these struggles (or at least, their material basis for being a struggle) intersects at class.
And that therefore, the best way to ensure everyone's rights is through the class struggle.
The US had to fight many decades for women's rights, and many more for black people's rights.
But in the GDR, USSR and Rojava, it's included in the package.
Ultimately, the left needs to get rid of the image that it's only for minorities. The white male worker shouldn't feel afraid he would lose his voice.
Nobody wants that.
