Your comment made me smile because your not having a precise source reminded me of an exchange between two people in a chat room:
Some stranger: "Masks are ineffective"
Leftist: "By not backing up your claim with any kind of source, I can only assume you're a troll who intends for people to kill each other by not wearing masks."
When asked about it by other people, the leftist dug their heels in; they believed their statement 100%.
