Because they feel affronted and so this is “perfectly acceptable” revenge/payback. They do it with everything… It’s also why they’re ok with dictator Trump. When he says in plain English that he is seeking revenge they feel the same way and want the same thing because revenge implies that they were initially “wronged.”
They always play the victim, it’s so absurd…
People: “Don’t be a raging racist asshole, just treat all people with respect.”
The right: “WAHHHHH! THE LEFT ARE AUTHORITARIANS WHO HATE US!”
