You actually have to identify what I said which you think is "bollocks".

Somehow you forgot to say what it is.

Terrific. Provide a surjection from N to R.

You are supposed to either say what you think I said which is bollocks,
or provide a counter-example to Cantor.

As it is, you are just mumbling.

The cranks should be pretty obvious. Clearly Madigin is not a crank,
but there are many others who are also not cranks. Anybody who claims
that Cantor's proof is false without identifying an error in the proof
is a crank.
