Of course the Order wasn't perfect; no organization is. I don't even think it's necessarily a sympton of their demise or ALL organizations would fall apart, although I do grant you only the Order had a Sith lord actively plotting its demise so maybe I'll concede that point. I also concur about the comment being directed at Jar Jar. Obi-Wan's sarcasm was his (sometimes not so nice) sense of humor which thankfully he toned down with maturity. That's not to say Jar Jar didn't earn a modicum of eye-rolling or somesuch from those so inclined. However, the comment was IMHO directed purely at Jar Jar individually, not Gungans in general.
