He's grasping at straws. First he has to label the video guy as "far right" when he'd rather say "racist" except the guy is speaking out about the police killing a black man so even
@Uncleskinny has the intelligence to know that wouldn't work.
Then he's unhappy with the post itself because of the "far right" video, and because he needs a reason to express his obsessive love/hate for Morrissey he also has to discount the animal rights video as some sort of trick/scam.
He is very close to being that man who everyone on the train avoids when they go into a rant.
