“Male” and “female” are, biologically speaking, not distinct and mutually exclusive categories in humans.

They are and you repeating a claim without evidence does nothing.

Sexual dimorphism is real and artificial means of changing or replicating some parts of sexual dimorphism does not invalidate the underlying biology at play.

Male and female are so indistinguishable that it’s possible to identify them by their pelvis alone.

It’s a term coined by bigots to misgender trans people

Unfortunate origins aside male is jot a gender and therefore not misgendering. Biological man is misgendering.

What do you think will be the outcome of arguing that sex and gender are the same? That’s literally the side of the argument you have chosen.

Either they’re separate and gender can be changed or they’re the same… and you disagree with trans rights.
