On the left, if you’re a leftist, you support leftist causes. You may be a BLM or a BLT or a transectional feminist with an interest in deconstructive criticism, but you support all the leftist causes and they in turn support your cause. It’s a way to make them appear to have more support for each identity group than there really is.
The enemy calls that "intersectionality", I believe.

On the other hand, capitalists are united by a system of production where, in general, the activities of one do benefit the all (WWG1WGA).
The leftist Frankenstein you described produces nothing. In fact, its purpose is destruction.
When not deconstructing, the Left is nothing but a parasite on the capitalist elements that manage to survive in their malignant presence.
