You've hit on a very crucial property of "liberals", which is revealed by this and in other ways, particularly when the subject of secession comes up in the US. That is, "liberals" are the worst violent supremacists ever, and essentially want conservatives as a slave class.

I mean, if you really disagree with someone, then you want nothing to do with them. If you're both in a club of some sort, then either you're going to quit or they are. Same if you were employees in a business or lived in the same neighborhood. But that's not what we see with these Leftists.

They know subconsciously that someone has to grow crops and drive trucks and build buildings, etc., and they consider such occupations unquestionably beneath them. What to do? They want the government to bring these uppity negroes of all colors to heel. If it is necessary to execute a few in order to get them back to work, they have no objections.

Look where Leftists draw the line against using violence. They don't. This dynamic is not to be underestimated.
