He's being funny, but he highlights the main theme of the Trump era:
Trump says something insanely stupid, something people who otherwise support him know deep down, is stupid... and then instead of addressing what he said head-on, they take what he said and work *backward* to engineer a convenient explanation of what he meant. It's happened so many times in the past years
Isn't it old? Some people will support him no matter what, but for the rest of us, doesn't it get exhausting? Do we really want four more years of this ****?
