The first time I heard of it was Eight Months ago when I watched a Youtube Video of Lauren Southern on Theryn Meyer's channel.
I guess the lib's are masters at controlling the language.
Liberals have had to up their name calling. “Racist” doesn’t work any more, so now anyone they disagree with is a white supremacist, or KKK member.
Liberals only control the language (or anything else) if you let them.
Call them on it when they do it and they immediately slide back into the darkness like the cockroaches they are.
