It isn't a very nice answer, but by adopting a tactic the left has used for some time, freeze and isolate the target (Alinsky), and crush that individual ruthlessly. Winning an engagement won't be enough, that individual must be hounded afterward and his or her life ruined by any means necessary and as publicly as possible. Activists are, mainly, terrorists and bullies, or rather a self-supporting network of bullies swift to come to one another's defense in order to keep the game going and minimize the cost of their aggression. And until there is at least a possibility of that cost being insuperable it will continue.
That requires a certain vindictiveness that is difficult to muster among people who truly believe in forgiveness and reconciliation, which the current Left activists most certainly do not - they want us dead and are not in the least reluctant to say so. You don't fight that sort of individual with half measures. All IMHO and regretfully posted, but I think it's the case.
