It’s always very inconvenient when left-leaning, progressive, liberal (often educated, critical thinking) people start opposing something.
It means that, just maybe, there might be something in it.
When those people happen to be women (inevitably, because it invariably impacts on them), it’s super-easy to patronisingly discredit them.
Throw ‘(ultra) right wing’, ‘conservative’, perhaps even ‘Christian’, certainly ‘Nazi’ is a quick, easy one - at them, and a). they’ll shut up, and b). all the other ‘progressives’ will distance themselves from the position at the speed of lightening.
It’s a tried and true tactic, straight from the Women - Shut The Fuck Up playbook.
