Don, thank you very much for the information/link re "argumentum ad hominem". A useful guide indeed in navigating debates ... ah, there's so much to learn!

And I'm glad we seem to have parallel dreams! I'm confident that dreams DO manifest, even the grandest dreams, when enough of us choose to make them real. It's just very unfortunate that it's the dreams of certain of our "world leaders" - ie. the creators of the "New American Century" manifesto - that are manifesting right now ...

Ireland, re the "tu quoque" argument - no, it's not quite the same, because I do not "freely choose" to pay taxes (ie. I'm breaking the law if I don't), whereas I do "freely choose" my career - and most thankfully so!
