WM keeps claiming that any system which allows a set of ALL natural number to exist is necessarily inconsistent, though he has not produced anything that qualifies as mathematically or logically valid proof.
WM must have skipped plane geometry as a child, and ever since, as he has no notion of what constitutes a mathematically valid or logically valid proof, but argues more like a politician.
