What's Mallard raving about today?
Honestly, this almost defies commentary.
Simply juxtaposing a topic which bothers you with Dinosaur extinction is not a formula for, well, anything except extinction (real or metaphoric).
Obama's Europe visit was history by the time this was written (let alone published) and the visit was in no way detrimental to Obama, except among a segment of the population that was/is/will be predisposed against him. So the trip could hardly cause a real or metaphoric extinction.
At a minimum, Mallard, is it too much to ask that you make a modicum of sense?
