Josh, your story reminds me of an old phrase of Bill Buckley’s: “the street theater of the Left.” They are very good at it, and they never cease. The obnoxiousness endures, day in, day out, generation after generation.
What is relatively new, I think, is the targeting of individuals, rather than institutions: not corporations, governmental bodies, etc., but individual donors, advocates, and others — and at their homes.
Should conservatives engage in this kind of “theater”? Sometimes tit-for-tat is called for, but I don’t think most of us would want to stoop to it.
(Benny Hill had a bit about “tit-for-tat,” which I might tell you about some other time.)
