"Mansplaining" is the clearest example of this. Supposedly it's only used to describe a man condescendingly explaining something a woman already knows, but in practice it's used to belittle and condescend any man criticizing a woman or women as a group. i.e. "Google employees are furious following the internal distribution of a memo mansplaining away low diversity in tech"
The only constant is the preconceived notion that they always know who the victims are ahead of time. The reasoning is then reverse engineered to suit the situation.
A man is talking based on feelings and anecdote? He's ignorant and pathetic, and probably needs to get laid. A man is citing scientific studies and making a cohesive argument? He's a mansplaining dudebro here to dogwhistle sexism and racism. If it's woman though, she's respectively sharing her lived experience and fighting the endemic patriarchy by being forced to work twice as hard as any man.
