The Sturgis rally is largely held outdoors.
So I fail to see the logical difference between a bunch of people, mostly outdoors, not socially distancing, occasionally going indoors whether it's to get a beverage or steal the latest Air Jordans.
Antifa does get a nod for wearing masks though.
All that said having the Sturgis rally was stupid, irresponsible and probably deadly for perhaps a thousand or so people.
