I’ll put it simply:
As Real Americans constant argue over which is the correct ‘Hill to Die On’, the promotion from a government entity of transgenderism and attempting to force it on to a population is ‘Casus belli’.
You’re exactly right. Every one of these assaults on normal civilized life is a hill worthy of dying on, if we care anything about stopping the destruction of reason and morality. We have gotten to where we sadly are now via small incremental “progressive” victories that most normal people considered not worth fighting.
