One of the problems with the way we characterize events and situations is taking the description of them to the point of ad absurdum. This often indicates a wish to damage or destroy rather than correct wrong ideas. There is plenty on the left that is ridiculous and dangerous. But exaggerated thinking is not conducive to correcting misbehavior, it only encourages it. The elimination of one side will not fix things. As soon as they are eliminated the members of the other group will find those who are thought to have been with them do not have the purity of thought they are supposed to have, and will have to be eliminated.
