This was already explained to you earlier in the thread. “Male” and “female” are, biologically speaking, not distinct and mutually exclusive categories in humans. This is the case naturally, and the terms become even less useful once you account for those who modify parts of their biology, whether by surgery or by artificially triggering natural biological processes, to bring those parts into congruence with other parts of their biology.
“Biological male” is a slur. It has no basis in science. It’s a term coined by bigots to misgender trans people with sciencey-sounding words so their abuse looks reasonable at a glance, in much the same way that proponents of Scientific Racism use pseudoscience in an attempt to legitimize white supremacy.
From the article:
It sounds like you can still get pretty far by just addressing the actual concerns of the working class and offering real solutions to problems. Still an uphill battle, definitely, but maybe not an insurmountable climb.
