Dear fom I'm not against Uncountability, I'm not against Cantor's argument. I'm saying that Cantor's argument is CORRECT. All what I'm saying is that it is COUNTERINTUITIVE as it violates the Distinguishability argument which is an argument that comes from intuition excerised in the FINITE world. That's all.
