And BTW, people are often too stupid to make their own decisions. That’s just a fact.
You answered half of your own question. There absolutely are people who seek power over others. I don't know if they are more concentrated in the political left or the right (probably the left right now just because it seems to have the upper hand). If you're lucky, they are trying to exercise power over you for your own good--if you're unlucky, yes, there 1000% are people who get sick pleasure out of exercising power over others just because they can. And when you add in an (un)healthy dose of the culture warring that has poisoned literally everything in the United States, well. People absolutely LOVE exercising control over their enemies. So yes there are people in high places on both sides who would absolutely implement policies just to immiserate the other side and would get joy out of doing so.
The mask mandate is a great example because while medical masks such as N95's in indoor settings are effective, clothe masks do little, if anything at all and wearing masks outside has been completely unnecessary throughout the entire situation outside of extreme situations like a packed outdoor concert or something. Yet, many blue areas implemented outdoor mask mandates and as far as I know nobody ever mandated N95 or other medical masks instead of clothe masks. This is just as unscientific as proclaiming that masks as a concept are universally worthless, but many of the same people that "trust the science" dutifully line up to wear their masks outside on a bike ride. Just as the rights bias leads many to believe masks are worthless, the lefts bias leads many to way over emphasize the importance with things like outdoor mask mandates or mask mandates for vaccinated people. At the end of the day so much is poisoned by the culture war, virtue signaling, etc that people can hardly even think straight.
It's perfectly rationale for people on the political right to be anxious about any actions taken by left wing political figures and immediately suspect that they want to hurt them--because they do!
