This is the Kobayashi Maru of interview questions because no matter how you answer it you will be shot out of the sky by the Klingons.
If you say that you agree with all the policies then you aren't answering the question and you look like a brownnose.
If you actually pick something and do an effective job of dismantling the reasons for its existence, then you could threaten your chance of getting the job.
Actually they are looking to see how you will be able to work under policies you don't agree with so what you can do it use an example from a different job that had a policy you found repugnant and how you handled it.
That way you avoid the tick question entirely.
