I understand your concerns but I'd argue that it is a bad idea to make it so that women are automatically shielded from any kind of scepticism. There is a sensible middle ground here between "All women are lying harpies" and "Women can not be criticized at all without it being dangerous and misogynistic".

I think it's also important not to conflate an accusation somebody of benefiting from a partner's nepotism as equivalent to accusing them of sleeping their way to the top just because they're a woman.
