of course....
It certainly is a ad hominem attack by every definition, unless we are going to change definitions to suit or own opinions again? Stating that a persons words can not be valid because they don't practice what they preach is silly. If Richard Nixon said that breaking and entering is a bad thing to do, would that statement be wrong because he was involved in a breaking and entering? Even if I prematurely put trees in bonsai pots, it does not invalidate the statement I made that some people rush trees into pots...get it?
Make the argument for or against rushing a tree into a pot, but don't attack the person, and yes, Al's comments were an attack, a ad hominem attack, which only serves to move the subject to the person and away from the subject....for proof of this in action see this very post, he succeeded.
Chris, you are certainly intelligent enough to know this.
Chris, this is not the first challenge you made and backed out of, I am surprised you brought it up though. I see no reason you were surprised at all, you said you would post a tree in the contest when I did, I agreed to and you backed out...why would you expect me to keep my end of an agreement after you backed out of the very challenge you yourself made? You challenged me, I accepted, you backed out....and I was ungracious?
Please.
