It's
the Day's Day of Days! Because English Summer.
We've seen this cartoon play out countless times--a character who's been happily all in on whatever's the latest brand of chicken-fried fascism, suddenly starts, out of nowhere, wondering if it's a good thing they're doing, and another character explains it as just and necessary as a result of the Left's evil, with copious mounds of Muir's patented projection, up to and including the projection of his projection. Usually, it's Sam and Zed, which of course, only makes it more awkward, because Sam's most consistent character trait is that she gets to be Muir's nasty cross-gender id, shrieking out all the things he wishes he could say in for-real public, instead of just in his weird little webcomic. But, frequently what he needs in those moments is for Zed to mansplain to his woman, and so Sam does a temporary 180 to allow him this luxury. This time it's the twins, and while it's slightly less awkward, ultimately, it's another illustration of how the hivemind exists not as characters but as puppets for Muir to speak his "Truths". If that requires you to just flip your personality for a cartoon, well, so it goes.
You'll notice I'm largely avoiding the politics of this strip. Not much to discuss, really. Just the usual vileness, and Muir being in this really awkward place as regarding the Kirk killing, which remains a difficult thing for him to parse.
