My Alexandria, Virginia neighbors are fond of simple-minded and obnoxious virtue-signalling signs, as I discussed here.
Another one has started popping up, this one proclaiming “Dissent is Patriotic.” As a general proposition, little of value can be stated in three words, especially those with “is” in the middle. “Dissent is Patriotic” is a gross generality, and a sign like this bolsters the delusions of smug absolutists and the historically ignorant.
The ACLU has been pushing this slogan (to sell T-shirts, it seems), and it had a re-birth thanks to the NFL kneelers, who are in truth a perfect example of when dissent isn’t patriotic. Incoherent dissent isn’t patriotic: it makes all dissent look bad. Dissent based on hate, lies, or a desire to divide isn’t patriotic: it’s hateful, dishonest and divisive, which is to say harmful, and thus unethical.
Speaking of dishonesty, many of these signs use the phrasing you see on the left, which is a fake quote attributed to Thomas Jefferson. Attaching a dubious assertion to a much-admired historical figure is an unethical propaganda tactic employing a dishonest appeal to authority. (This is a famous example.)
As Ethan Epstein wrote in The Weekly Standard,
Few if any Americans are associated with more apocryphal quotes than Thomas Jefferson, but the false notion that he said, “dissent is the highest form of patriotism” is among the easiest to dispel. Because Jefferson never would have said something so idiotic. Of course dissent can be patriotic, but it isn’t inherently so. What one is dissenting from matters. Were members of the German American Bund, who protested the U.S.’s anti-Nazi policies in the 1930s and ‘40s, enacting the “highest form of patriotism?”
