What science or expert do you trust?

"According to the epidemiologist Sunetra Gupta, you should do just about the opposite of what’s being preached by college presidents, teachers’ unions, political leaders, and the scientific and media establishment. Unless you’re elderly or particularly vulnerable, you shouldn’t be wearing a mask all day, or shaming others for going unmasked. You should be careful not to endanger the vulnerable, but otherwise you should be exposing yourself to the virus in order to promote herd immunity."

I was a medical librarian for 14 years, agriculture for 3 and I used to translate medical journals when I was a grad student.  If I'd ever tried to present my clients or employers with the mish mash of so-called politicized science we've heard the last 6 months, I would have been fired. I have no idea if Dr. Gupta is right, or whether 6' is the optimal number, or whether masks do any good.  This I believe: the elderly, like me, are at risk; those with other health conditions like smoking, diabetes, obesity and lung diseases are at risk even if not elderly; and rioting and looting and taking your exposure back to your family puts everyone at risk.
