I love this paragraph from @pluralistic :
"Populism," is shorthand for many things: rage, despair, distrust of institutions and a desire to destroy them. True populism seeks to channel those totally legitimate feelings into transformative change for a caring and fair society for all. So-called "right populism" exploits those feelings, using them to drive a wedge between different groups of victims, turning them against each other, so that elites can go on screwing the squabbling factions.
