Nice refutation, well considered and poignant. Good example of the hashtag's reluctance to engage with specifics. Thanks for the help.
*sigh*
It's called metonymy. Or, I guess more specifically, synecdoche. It's a literary device, in the above example used as a way of lessening a gender. The 'influence of vaginas' thing was/is? a fairly common phrase used on Gamergate sites 8chan and KotakuInAction.
If you outright deny that large aspects of the hashtag inescapably align with anti-social justice issues, then you're ignorant or a liar.
My point stands: "fighting against the corruption in gaming media" is deceptively vague and demonstrably untrue. The hashtag is fighting against a very specific kind of perceived corruption ('SJW's are secretly trying to manipulate our media), to wit, a conspiracy theory.
