You won't single them out. In fact, you have people down that aforementioned hallway who will legitimize the moronic idea that black folks are justified in basing their refusal to vaccinate upon the Tuskegee Experiment and other paranoid conspiracy theories. You're not that stupid. Maybe some of your colleagues are, but you're not. You're just too cowardly to be intellectually consistent on this count.
I love the premise that a free test is still unattainable. I've seen this mental contortion floated before when the intensely uncomfortable data reveals the depth of resistance among blacks is unavoidable. Give me a specific example of a locality in the lower 48 where people interested in getting vaccinated are unable to get to a vaccination site. We're not talking about difficulty in getting a poor black American with cancer to a proper oncology unit, we're talking about getting to COVID vaccination site. Please, share with me where connecting anyone with this kind of site is preventing the willing from becoming vaccinated. Pick a state most conducive to this gymnastics routine. Pick Mississippi. Or Alabama. You choose. Where is there an inability to access a COVID vax site where people who are open to vaccination are being dissuaded from vaccinating because of a lack of access?
