>I do not at all see how putting quotes around that word invalidates the argument
When the argument is:
[0] is very, very much is [natural for indexes]
and as an example for that points to something that's not an index -- and the person making the argument knows it is not an index, so they have to put index in quotes:
Polynomials all start at a zero "index"
...then pointing this out, does invalidate the argument. It might not prove that the opposite is true, but it sure does invalidate the argument.
Notice also how there's no ad-hominen in my response (this or the previous one) as you claim. I argue against the case and the choice of example, not against who wrote it.
