Ah, the original post by Guy Chapman only mentioned the nutjob article, not the original Canada Free Press one, and gave the mistaken impression they were the same.
Judi McLeod's article carries the often-repeated mistaken idea that it was hard for Siegenthaler to remove accusations from his article. It wasn't; it contained them for so long simply because nobody noticed. It's easy for anyone to have unsourced allegations removed.
And the whole freemasonry thing is a bit nuts, if the above is correct and the Kofi Annan article never contained it in the first place. It sounds like that someone so loves the conspiracy-theory version that correcting the facts doesn't work.
