first off, covid-19 is a virus, not bacteria, but ill let that slide because it doesnt matter. second, covid-19 is transported by aerosolized water droplets. if youve ever used spray paint, understand it does not get picked up by the wind and carried across the ocean. dust is less dense than the stuff that comes out of our mouths. third, experts have looked at how the protests have affected covid-19 transmission and found no significant effect, as your link says. that talking point is kind of dead.
the reason the us has so many more deaths than all the other countries can be explained by the president not creating a national plan in time and trying to reopen the economy before it was safe to do so, as well as his gross downplaying of the severity of the pandemic. i know this is a hard pill to swallow, but trump is kind of a dumb rich guy who's playing you very hard.
