#1 - How are you applying this to Trump supporters? What is meant by “all-encompassing”? See #3.They 1) espouse an all-encompassing belief system; 2) exhibit excessive devotion to the leader; 3) avoid criticism of the group and its leader; and 4) feel disdain for non-members.
#2 - The devotion (actually a bad word for it. “Loyalty” is more accurate) comes from the fact that he moving in the right direction. It’s about the actions, not him. It’s the policies, not him.
#3 - This definitely doesn’t apply. Take a listen to Moleneux when he bombed Syria. Take a listen to Levin (or just about every other right leaning YouTube channel or radio show) when he signed the last spending bill. If you think there is blind devotion, you are living under a rock. But that is the difference these days between the left and right: the right is willing to be critical when it compromises princliples, the left will do whatever it need to do to advance its ends, even twist itself into philosophical knots.... or call people cultists or useful idiots for Russia.
#4 - Nope. I have a lot of family and friends and workmates that do not agree. But if they put on a pussy hat, yeah, they deserve the ridicule.
