I don't think it's fair to hold Ali G against Rooney. Guy is eighty billion years old. Nobody from his generation would recognize the joke that is Ali G, however good their sense of humor.
There are plenty of legitimate reasons not to like Andy Rooney. Use them.
Refusing to go along with Ali G is legitimate; I considered Rooney to be one of the show's "winners." Losers _want_ to stop, but just keep going because they don't want a confrontation.
if we live that long, in the end we all just become a sad old thing that watches other old things go into the abbess while we are forced to wait our turn.
