You are correct to question those "con" statements about IPIX, Michel. My intent is to show the contrast between the pro and con arguments, with a clear bias to the "pro" side.
So many of the "con" arguments offered about IPIX are false, ludicrous, silly, trivial, defamatory or worse. I've selected only a few of the "cons", while the "pro" arguments can be independently verified.
When one looks at the arguments on both sides, the comparison should speak for itself.
