Please look at the account of the person who hosts that video you are watching that makes the leftist being trashed in the thread look bad. It's usually filled with garbage about how the Okay Sign isn't racist, or how Star Wars The Last Jedi is a really bad movie and how JK Rowling is allowed to think whatever she wants and people should leave her alone and shit like that.
That video that you searched youtube for to find the receipt for the accusation you heard about in passing was almost certainly uploaded to a fascist's channel, and you just linked it to people.
