The troubles began when L. Walker said Iain Davidson had a true proof:


Mr. L. Walker, and here is Iain Davidson's attempt that you endorsed
as true:

Trouble is that L. Walker never pointed out that w+1 is divisible
by w+1 and divisible by 1, and since none of the primes divides into
w+1, that w+1 is necessarily a new prime.

Hence there is no contradiction to 2) and hence no proof.

So until L. Walker admits his mistake of approving a fake proof, we
are just going to see
more rudeness and a deterioration of math posting from the UK.

Usually the people of UK are overly polite and deem our praise on
their politeness, but I guess
every barrel has its rotten apple.
