I don't agree with most of the critiques in the comments of this meme because I don't think they get to the heart of the problem. It's not a perfect analogy because "them thinking" doesn't logically translate very well to "is mandatory". The first frame deals with how people think while the second frame deals with the reality of a situation. The honest truth is that while the vaccine may be dangerous, it's not as dangerous as literally injecting bleach.

The way to make the logic perfect for this meme is to say "Trump suggests people should inject bleach to cure COVID" and then the second frame says: "Biden makes injecting bleach mandatory to cure COVID". In that sense, the logic would make sense, but obviously that's not the reality of the situation.

So I guess the flaw is that bleach and the vaccine are on different danger levels and this meme implies that a chemical vaccine injection is as dangerous as injecting bleach. It's hard to explain but that's basically the gist of the problem.
