Because both of these came up today, and though alone I was cursing audibly.
Whatever advantage Celsius/Centigrade has for scientific and international purposes, it is inferior to Fahrenheit for everyday use. Anything below 0° is Too Damn Cold. Anything above 100° is Too Damn Hot. The rest is commentary.
The right wing radicals are primarily defensive, not only threatening to hole up with lots of weapons, daring the ATF and Biden to come after them but actually doing it. You can hear them say some truly frightening things about the race war that they have been sure is coming for thirty years or more and how ready they are for that. They shrug at the idea that they might have to shoot some people. But of the ones I have met here in NH, none have said "I'm gonna go down to Concuhd oah Manchestah and look foah some o' them radicals and blow theah fuckin' heads off." It just doesn't happen, and nationwide this seems to hold as well. They are serious. But they are staying home protecting their stuff. The left wing radicals are absolutely willing to go downtown everywhere and be aggressive, lighting things on fire or taking over buildings or neighborhoods or looting. But there is (was) a reluctance to even talk about shooting people. Each feeds the paranoia of the other by the limitation they don't care much about. The right wing looks at itself and knows it would not go out on offense unless they really felt the Republic was in danger today; the left wing believes that actually going after human beings is a bridge they will not cross. (There have always been exceptions to both, but...)
My fear is that both limitations are breaking down, both fences have been breached. The generation one down from me seems mostly okay on both sides, with worrisome features. The next generation after that does not adhere to those norms, left and right.
