Why do NPC's attack you if you don't accept their gender?

Why do NPC's want to force you to vax even now?

They've mutilated their own children and know they have ruined their child's life. They have to keep believing the lie or the true horror of their actions would destroy them.

They know the vax is killing people now but they have to pretend it isn't happening and force you into the same hell hole they've dragged themselves into.

They fell for the lie and need you to fall for it so they can forgive themselves.
