Estimates in the Chicago Tribune are that “thousands” participated in Chicago alone. That number is off by a couple of by a factor of 100 at least. The march I attended in Santa Clara, CA had about a thousand people, and it was only one of many marches and protests just in San Jose. Assuming there were at least a few 100 such marches, with about a 1000 each on average, it would be much more accurate to say “close to a million celebrate with antiracism marches”. But the MSM, and apparently even The Guardian, chooses to downplay anti-government civil disobedience movements, going at least as far back as the Occupy movement.
More than a thousand people are murdered by uniformed thugs in the US each year in extra-judicial incidents. About a third of the victims are Black, so let’s say about 400 a year. Assume only 2–3 of their family members show up to march on Juneteenth. That is already a thousand people in anti-racism marches.
Here is another MSM mealy-mouthed statement (or perhaps it just reflects innumeracy) with the quantifier “many”.
Many? “Some” means more than one, so single digits. “Many” can be reasonably construed to be between 10–100 as an absolute count. As a percentage, “many” brings up 10–50%. Anything greater than 50% would require “most”, “a small majority” or “a large majority”, up to about 90%, at which point one would say “an overwhelming majority”.
As far as the civil disobedience movements against police violence motivated by the extra-judicial killings of Breonna Taylor and George Floyd by cops, of the thousand or so people I must have encountered in one march in Oakland, not one was without a mask. So even I missed a few, the truth is closer to “with countable exceptions, all protestors wore masks, …”.
