I dunno bro, I saw a lot of bright smiling teeth behind him DURING the joke. Not a single person I know with a soul did anything other than gasp. The entire rally was full of opaque out and open fascist statements and disgusting needlessly aggressive remarks about opponents. If you think it wasn’t similar to the MSG Nazi rally then you really ought to watch it. Your blinders are letting you get slow-walked to nazism.
Sorry bud, you’re not a republican any more… They’ve left you behind because your morals were based on something.
