Thanks. I don't understand much of what points they're trying to make and disagree with some aspects of what I do understand.
They seem to be saying that intersectionality is a dilution of power welcomed and promoted by the powerful. In fact, intersectionality as a philosophy of struggle was invented by the financialists in the 1970s as they struggled for their very existence. They applied a number of different labels over time, the most common of which is "big tent conservatism". It is how they gathered everyone from Christians to social conservatives into a battle against taxes, publicly funded social programs, publicly owned infrastructure, regulation of corporate activity, and the employee class.
The usual thing is for the right to steal the language and symbols of the left and turn them into insults and symbols of their own power. It happened with the swastika, it's currently happening with the Canadian flag, and "woke" has been turned into an insult so egregious that the original owners now fear to use it.
Intersectionality is, for a change, the left stealing from the right. Given that the financialists invented this philosophy, it should come as no surprise that they know how to twist it to their own ends. But that doesn't mean we should let them divide us for conquest.
