Again, this is a bad idea, perhaps with food intentions. Most terrible events in history didn't start off at their worst, they started with things like "papers please" or indoctrinating people that "those people aren't like us" and in many cases end with mass amounts of people killing each other and in most cases it could have been prevented by not giving into the "papers please" mentality.
I am fully vaccinated, that was my choice though and everyone should be free to make their own choice.
As far as the optics go, having had the chance to speak with several African American people, for the most part, they don't trust the government or the vaccines and the ones that do, don't trust the medical companies not to bill them. Considering my insurance tried to bill me for the second shot, I understand the last one. Not sure how you can overcome these issues When the mandates make them even less trusting.
