You're the one who made the assertion of "mostly have herd immunity" so the burden of proof is on you. In any case, my point wasn't about that (though I don't think we've reached herd immunity yet, and with all the outside visitors it doesn't really matter for the percentage of the population that isn't immune). My point was that the phrase "mostly have herd immunity" doesn't make sense.
I have no burden of proof. I thought the emoji I put there meant tongue-in-cheek, CMIIW. I honestly don't care what the person I was referring to decides to do. All I posted was an anecdote or DP, you decided to try and make sense of it, so I decided to have some fun.
