Heheh, maybe the first time in my life I've ever been categorized as a Left Wing Activist. I kind of like it!
Wear a mask. It's not that hard and it's not a hoax.
I have certainly called for some more rigorous studies on exactly what mask materials/densities/layers etc. work best. It's difficult for me to fathom that we're 4-6 months into this thing depending on where you live and what date you start counting, and we still don't have some basic published studies on the effectiveness of N95 vs surgical vs 2-sided fabric vs bandanna vs scarf. Because as I've said many times, if wearing a bandanna or a scarf really doesn't do anything, then we shouldn't be asking citizens to do so, and instead we should be telling them what DOES work and how to get ahold of it, and even providing it to citizens for cheap or free where possible.
As I stated back in March, the problem is that, starting from the first words we heard about this, we were on a timer. We're using up our goodwill, we're using up our "COVID capital," with the public. So telling them to do things that aren't actually beneficial, is not only a waste of everyone's time, but it will also backfire and result in WORSE behavior. Antagonistic behavior. Rebellious behavior.
I was saying this back in March, and well, here we are.
Even so, wear a mask. 2-layer cotton, surgical, whatever you can get ahold of.
