I guess you haven't been paying attention. Plenty of people have suggested numbers when restrictions might be lifted. I mean, they weren't "Right this instant," so I can see why an anti-masker would gloss right over them...
I've seen numbers as low as 65% of the eligible population vaccinated, with case numbers around 5 per 100,000. So...there are your numbers. What, you worried that won't happen? Blame your anti-vax friends, then.
We are still giving out well over 2M vaccines per day in this country, so clearly demand is still high. Weird that the "supply" of the vaccine doesn't instantly appear in people's veins after it rolls off the assembly line, huh?
But no, we must drop all restrictions right this instant, and everyone who doesn't ignore the fact we are still in the midst of a global pandemic is just power-mad with their new-found ability to make people wear cloth over their mouths.
