Here's an "acceptable" use of the diagonal argument: Given a provably well-defined list of provably well-defined real numbers (so that every digit of every number on the list can provably be computed), the diagonal argument gives us a new provably well-defined real number not on the list.
Notice that that argument doesn't require the use of an actual infinite.

He most certainly did mock them.
FWIW, I was motivated to start this thread after reading an article you wrote about problems you had in your encounters with mathematicians who didn't accept your ideas. I'd like to know a little more about that, although I admit you really have no obligation to tell us more if you don't want to.
The mathematics community has simply lost touch with reality.
