Liberals cannot survive without a “cause.” They need something to protest against, even if it is something trivial. Their short-circuited brain requires them to feel good about themselves for some touchy-feely cause in which they believe they actually are doing good. They aren’t afraid to be loud and aggressive because, to them, it shows they really really care and that makes them feel good about themselves.
It goes back to Critical Theory which was hatched at the Frankfurt School.
They are not liberal. This is where we lose the battle right off the bat we start saying “these liberals” blah blah blah. They are not liberal. And until we start labeling them properly we lose.
