This post could easily go on the cultural divide thread, but I'm thinking here of how Covid became a source of that division. I think it ridiculous that a church would be offering prayers that God would "change the hearts" of the unvaxxed as though it were a problem of sin and repentance rather than differing assessment of the risks. Yet there is no question there is big division that is growing to the level of spiritual/religious, and it is exemplified by some of the debates surrounding vaccination.
I suspect that the source of the division is not Covid, but the approach President Trump took towards it. Folks who were already against him, considered it fool-hearted. His supporters continue to believe that it's no big deal; that he spoke/speaks the truth while Dr. Fauci and others are over-stating the problem.
(It seems to me that the dire predictions of Dr. Fauci that it wouldn't disappear are ringing more true than Trump's early assessment.)
It must be nice to be able to embrace such a simple world view. Whatever bad is happening in the world, it must be all Trump's fault.
The divisiveness that infects our country and the world is not of simple origin. Many of Trump's early predictions and assumptions concerning Covid turned out to be inaccurate or just plain wrong. So did early predictions of Dr. Fauci. (Remember his early predictions that Covid would turn out to be no more of a big deal than the annual flu season, or that people did not need to mask up to help prevent the spread?) And prominent Democrats. (Remember their assessment that Trump's early travel ban was unnecessary and xenophobic, that his plan to institute a "warp speed" vaccine development program to produce a useable vaccine by the end of 2020 was impractical and impossible, or that if a vaccine was produced that they would not risk themselves by taking the vaccine?) It has been correctly pointed out that the scientific understanding of Covid has grown, developed, and changed as new data was analyzed and the disease itself mutated. Strange, that makes early mistakes by the favored experts and politicians reasonable, but the early mistakes of Trump remain proof of his stupidity and foolishness and that of those who've supported him. Pres. Biden's recent travel bans because of the Omicron variant are prudent and wise, Trump's from early in the pandemic remain proof of his bigotry and that of those who supported him.
Those who say that Trump did nothing effective to deal with the Covid crisis have a very selective memory.
The divisiveness in our country predates Covid, predates Trump. Trump and Covid because excuses. Not that Covid hasn't inspired much fear that has fueled conspiracy theories, paranoia about the disease and the vaccines and treatments. Trump himself often stoked the divisiveness. A classic strategy for strengthening group cohesion is to organize them against a common enemy, Trump played that to the hilt. So have Democrats against Trump. Politicians, pendants, and ideologues have seen in the Covid pandemic an ideal opportunity to stoke fear and anger, using it to advance their agenda. The imperative, "Never let a good crisis go to waste" knows no political or ideological bounds.
