It’s another variation on Hillary’s “deplorables” theme, in which if you don’t support a good Democrat such as Biden, you are evil in some way. We all recall Hillary’s screed about how we are racist, sexist, homophobic, xenophobic, Islamophobic, you name it.
The liberals do not view their political opponents as opponents. They view us as evil, vermin, to be vanquished, not political opponents to be defeated in free and fair elections.
To be fair, Hillary only said half of Trump supporters are deplorables. But I’m also certain that she regarded the other half as chumps.
