Kata is not bullshido. In my style and the traditonal japanese martial arts. Kata is performed by two people. One person is the receiver of the technique. This means you actually touch the person. From the kata you learn how to perform the move. Then later you demonstrate how to perform the technique doing randori, kumite, sparring or whatever you want to call it. I think judo has kata like this but I'm not sure.
I can't speak for the Okinawan guys. I don't know about their katas. But I think it shouldn't be dwelt on too long. If you focus too much on it it's just a filler for classes. That's why it should be practiced more at home then in the class.
