The poll does not observe a wide spectrum of potential positions on this, partly by design, and partly because this is one of those that cannot easily be sorted out to "orthogonal", non-overlapping, options. Just choose the one that you feel the strongest agreement with. Your second pick just doesn't get the vote.
