Creating an unprovable incorporeal concept like “gender” and claiming it overrides a physical concept like biological sex is an attempt to use artifice to bypass the requirement for proof. This must not be treated as legitimate.
I oppose wrong beliefs and ideologies, not people. Had I walked in another's shoes, I might believe and do as they believe and do. I don't oppose people. I seek to persuade them. Wrong beliefs and ideologies are forever wrong, but a wrong person can choose to become right.
