Whoever got disciplined for this trolling shit should sue for that.
And even if it has been seen being used by white supremacists, well, it isn't like a white supremacist is going to devote every, single, waking, attosecond OF THEIR FUCKING EXISTENCE to white supremacist anything-ing!
White supremacists cook food, eat food, consume drink, shit, piss, sleep, and communicate other things when communicating, whether communicating with white supremacists or people who aren't white supremacists. So yes, at some point in time, the 'OK' hand sign will be used by some of them now and again. So will giving someone the middle finger, so will drinking beer. Does that mean everybody who has got pissed on lager and given someone the middle finger a white supremacist?
I bet yesterday there was a paedophile, a real dirty bastard who rapes little toddlers, who started the day not, regrettably, with having a railroad spike hammered through his wrists and ankles and genitalia to a pair of crossed planks before having his jawbone sawn through with a dremel tool and hismouth ripped off leaving all those nerves going to his teeth exposed, to be covered in chili pepper extract.
But unfortunately, instead, remained undetected, and who started his day's toddler-shagging with a cup of tea and a biscuit.
Does that mean I'm a filthy child fucker, because I ,like tea and biscuits too?
