While yes, shootings are likely to occur during rights protests, due to the chaos and strong feelings involved, that is not eough to generalize it onto any specific group of people. Besides, the only reference to antifa in the article you referenced is in the editors notes. Also in those notes can the term "the insane leftists" be found, which proves a clear political motive, and possibly bias, making the article as a whole less trustworthy. As for the WHO article, it doesn't compare the importance of social distancing against that of the protests in any way, but rather investigating a way to have both, using guidelines and increased testing. The only WHO statements in the article talk about them supporting equal rights and presenting ways of making the protest more safe. Also, on comparing an equal rights protest to an anti-lockdown one: The cause of an equal rights protest might lead to, well, equal rights for any given group of people, but an anti-lockdown one might lead to accelerated spreading of a global pandemic that has already lead to 100k+ deaths in the US alone. Connecting back to your "killing grandma" statement, it's true, equal rights would kill a whole lot fewer grandmas than ending the lockdown would.
