y'know when people make accusations of dogwhistling online, they usually mean that it's a plausibly-deniable way to find like-minded chuds
like this guy said he's glad there wasn't rap hoping that others in the thread would say "omg me too" and they would quietly start up a movement on era to influence the narrative or something
because if you're not trying to quietly "summon the dogs" then what the hell would be the point
but apparently everyone is instantly able to recognize this secret clarion call, which makes it not-so-dogwhistley, and I'm willing to bet that every user accused of being a racist transphobic nazi chud dogwhistle since the site's inception would deny it, not the least because you'd be hard pressed to find anyone on or off era who would high five you and say "sick dogwhistle bro"
all this is to say that the ban should probably just say racism
otherwise people might get the idea that "racist dogwhistle" means "so subtly racist that people would be up in arms if we called it that so we have to whole cloth invent an insidious mentality for the user that makes their statement worse than it actually is"
