"Proofs" that violate mathematics, namely:
For all n in |N: f(n) = |{n, n+1, n+2, ...}| > 10 ==> lim f(n) =/= 0.

But even accepting those "proofs", we find that no system satisfying the axioms IV and VII of Zermelo's 1908 paper can be countable.

Luckily myself and many of my students understand that.

I understand that proper use of universal quantification shows that universal quantification is impossible for infinite sets.

For all n in |N: unversality is not established.
