Comedy can be and is used to make real criticisms of the world and various institutions. “It’s just a joke” is one of the most common lies.

People can laugh at the joke, or disagree with the criticism it communicates, or both, or neither.

But having and exercising critical thinking skills when engaging with memes in a meme community full of scholars and academics is exactly what I would expect.

x = 5/9 is not 9/9. 5/9 = .55555…

You’re proving that 0.555… equals 5/9 (which it does), not that it equals 1 (which it doesn’t).

It’s absolutely not the same result as x = 0.999… as you claim.
