I think the two-day meme is badly misleading. Having a candidate vaccine sequence on a computer is very different from "having the vaccine".
It looks like Moderna shipped its first trial doses to NIH in late February, more than a month later. I think that's the earliest reasonable date you could claim that "we had the vaccine". If you were willing to start putting doses in arms without any safety or efficacy testing at all, that's when you could start.
(Of course, if you did that you'd presumably also have done it with all the vaccine candidates that didn't work out, of which there's no shortage.)
Sorry, this isn't a very strong analogy.
Hanania doesn't criticise anything specific about the bills directly or offer a clear thesis for why they led to a rise in crime. There's no analogy to clubbing seals here. The strong implication imo is that giving more freedom to black people itself led to bad things happening because black people (according to Hanania) have a bad culture. Which is a different and much more offensive (to many) thesis.
(I agree that this is then used as a segue to a pretty insightful and biting critique of conservatives, which is the main point of the article. And I can see the pragmatic value of his argumentative approach for reaching racist conservatives. But I don't think that does much to defend against a charge of racism here.)
Assuming we're only talking about the post Richard linked (and the user's one recent comment, which is similar), I agree with this.
