AGPs hate their mothers. They're morose, depressed men, so they hate existing, and their moms are the reason they exist. Their moms also got pregnant and birthed them, something that they envy. Everyone has a female mother, and that flies in the face of "biological sex isn't real" and "men can totally become women". Plus, mothers and manbabies are often natural enemies - who tells you to put the toys away, move out of her basement, and get a real job? It's not surprising that the troon squad saves their worst venom and most shameless grifting for the moms of the world.
