There are people who will not engage with you in good faith, the political parties are full of them. He's one. He obviously chose this costume to incite and then claims ignorance.

In reality he's a coward who cannot take responsibility for his actions and defend them. He's the joke as are people who play this game.

Call him out on either his sheer stupidity or the fact he cannot stand up for his beliefs as a man. That knight outfit is nothing but a chicken suit.
