"America." The people who have these red MAGA hats and other paraphernalia have no idea that "America" refers to not just the United States, but to the whole hemisphere. And for the most part they don't care. What they want to "make great again" is just the little part of America that's in the US.
And actually, they can't even do that, because the US has never been "great," and therefore cannot be made "great" again. The US has, for its entire existence, been a nation built on exploitation, oppression, genocide, and internal colonialism; a nation built on two kinds of slavery: chattel slavery (people owning people), and wage slavery (people owning other people's labor).
Republicans. The people who yell "Make America Great Again" the loudest have no intention of actually doing so. They continue to block: efforts to raise the minimum wage, and thus make wage slavery a little less onerous; efforts to put in place a truly sane national health care system by eliminating the "health insurance" industry; attempts to reform laws regarding the possession of firearms; elimination of student debt and extension of free public education to college/university; elimination of medieval restrictions on women's reproductive health care (and why are males even a part of this conversation?); etc.
Critics of Critical Race Theory. As far as I can tell, these critics don't understand the terms "critical," or "race," or "theory."
China. Yeah, China, for its obviously genocidal treatment of the Uyghurs, but also for its stupidity in mistaking communism for fascism.
Владимир Путин. He's on my list for wanting to reconstitute the old CCCP by armed force instead of making Russia a place these other countries, like Ukraine, want to hang with.
The Vaccine Refuseniks. These people who equate remaining unvaccinated with "freedom" and "liberty" are killing us. And they're pissing me off. If nearly all of them had gotten vaccinated when the rest of us did, we'd probably be pretty much over this thing. You know, like how we're over smallpox, and polio, and etc.
Educational administrators at every level. Mark Twain wrote: "In the first place, God made idiots. That was for practice. Then he made school boards." See the recent spate of Boards removing books like Maus (about the Holocaust) from their curricula, or banning use of the word "gay" in classes. People on these boards seem to work under the illusion that children are snowflakes. Well, they aren't. They're tough. They can take it, often better than their parents.
This is only a partial list; I'll be back.
