Of course they are angry.
They have spent decades projecting their beliefs, actions, and demeanor on those who disagree with them, accusing others of what they, themselves, have been doing. Naturally, with their tendency to consider an accusation, no matter how baseless, as a conviction, they are angered at the people doing all those horrible things. Yet they are ignorant of or refuse to see their own behaviour is what they rail against.
I see them doing it, and it makes me angry, but they are all the more so when those they accuse are innocent, and they can't get them to join their grifters' club.
