I think masks may be part of it, but primarily combined with people getting together in groups indoors.
The random person with no mask down the aisle of the grocery store? Probably not an issue.
A group of people without masks at parties, reunions, bars, church....well
As for the protests, sure they were a problem whether it was acknowledged or not...but from what I saw on TV, a higher percentage of people were wearing masks than in my church (where there is no distancing) yesterday.
Once people started protesting, I suppose we could have gotten out the fire hoses....
By not voluntarily doing things that may help, we are virtually forcing mandates...which a bunch of people will then cry about as unjust. The idea that people will not voluntarily distance or wear a mask in a store until it is proven to their satisfaction...by scientists they would never believe anyway...is absurd. There is no evidence they will accept. They've chosen up sides.
I estimated that up to half the protestors were wearing masks. The other half, not. They're doing some contract tracing now. Are the new infections coming from the churches? Bars? Parties? Reunions? Probably from all above. But, there is a reason why it's mostly young people. I'm not sure it's fair to blame conservatives for that.
It seems at least a little likely that the spike would have happened regardless of what conservatives believe about masks, given the predominate age range of people testing positive. Conservatives are getting all the blame for that.
