In the same vein, you could assume Democrats are more at risk because they put too much faith in masks, thereby entering more risky situations. Not saying that's the case. The point is, your expectation of who gets infected is merely your partisan belief, not anything rooted in evidence.
First of all, the disease doesn't care about your political opinion; it will spread in protests whether you are a crusader or an infidel. So it doesn't matter what you are protesting about; what matters is disease spread.
Now regarding BLM's purpose, which was police violence presumably. Police kill around 1000 Americans a year. Not an insignificant number but pales in comparison to the pandemic.
Trump rally, pointless, entirely your biased viewpoint. They were protesting the lockdown, which has crippled the economy, shut down a massive number of small businesses, made tons of people lose their jobs, and come January, will evict tons of people. Their protests had a point, but you're obviously misrepresenting them to fit your biases.
So no, your statements were not factual.
And I'm not defending some logic around the numbers of BLM vs covid, and it's unfortunate they coincided. I'm saying that the BLM protests had been bubbling for years and through a few incidents came to a real boil this year. I fully agree that it's irresponsible covid-wise to be out in the streets.
Feel free to disagree about scale, but what if the March on Washington of 1963 coincided with a viral outbreak. Should it not have happened? I'll respect your opinion, I'm merely stating that it served a real purpose, and it's hard to pick the right time for it.
