So, by your logic, Disney should get rid of Pooh?? I'm sorry, but that's just silly. No, you don't have to like or enjoy an attraction. But that doesn't mean it's time for that attraction to go. I think AstroOrbiter is a huge waste of space. But, that doesn't mean it's outlived it's usefullness.
Country Bear Jamboree is a classic. I would say it has pretty much stood the test of time...it's still pretty well attended whenever I'm in there.
Political correctness has gotten out of control. No ones sensibilities are going to be offended if they hear any song in there. And if you find you don't like it, then don't go back. But I really resent the implication that because there are some people that might be offended by something, that I can no longer enjoy it.
Personally? I'm offended by sushi...I don't see that going away any time soon....
