That's why "liberal" shouldn't be used to describe them anymore. The word "liberal" connotes tolerance. They are left-wing extremists, far left-wingers, left-wing hatemongers or whatever you want to call them. They only tolerate what they agree with and are intolerant of everything else. In other words, they're not tolerant at all. To tolerate something means to put up with something, whether an idea or behavior, that you disagree with. They are really fascistic, wanting to force their beliefs on others and are willing to lynch those who who don't agree with them.
