It was reductio ad absurdum, but there's a very large kernel of truth there that you pro-4E guys are failing to acknowledge and are pretending is a non-issue.
No, on the contrary, I don't care that much for dragonborn (and hated them in 3.5), and I haven't cared at all for tieflings since they were introduced back in Planescape.
As for gnomes, I've thought they were kind of an awkward race ever since 1e. They're a freaky add-on to a list of basic Tolkienish races, and are only considered "basic" on virtue of them being in the game for 30 years. If I were to guess, over the life of D&D, there were fewer gnomes played than any other race. That's certainly been my experience, since the early 80's.
I love half-orcs. Since I get
full orcs in 4e, I'm pretty okay with their absence - but still, I miss 'em. I wouldn't call them a basic fantasy race, either, but at least they're vaguely Tolkienish with the Orc connection.
On the other hand, my players - who range from pretty casual to very experienced - thought tieflings and dragonborn were pretty cool. I have one of each in the party. One of my players even thought the Gnome was cool, and is playing a Gnome ranger.
I don't care for the new races. I don't think it's an apocalypse.
