Divide and conquer is one strategy for dealing with opposition. Another strategy is deride and rancor.
Instead of a victory, which is perhaps unlikely any time soon, the goal is a sustained state of antagonistic belittlement. Derision and rancor don’t persuade or influence, but are instead an aggressive affirmation for the home team. The good news is that it’s pretty hard to humiliate anyone, liberal or conservative, into changing their minds. The bad news is that it’s pretty lucrative to try if you have the inclination, the audience and the willingness to do so. Ditto for Al and Anne.
