The entire republican party is currently lockstep saying all trans folk are trying to corrupt, if not molest, children. They're promising national legislation to oppress and punish them if they win. Before them, it was Mexicans and Muslims. They always have a group of "others" to scapegoat, and given enough time and power they always eventually act on it.

"Never again" means we're supposed to recognize and stop this behavior before it can harm anybody, not wait until it's too late as we disingenuously quibble over definitions.
