Do they have answers? Yes. But not ones I find very satisfying :-)
I don't think, though, that people must always have answers to contribute. That would seem to be a science-stopper to me, as frequently the precursor to the great scientific paradigm shifts is the building voice of problems with the current paradigm. It's OK in science to simply raise an objection. Of course we remember those who then find solutions, and that is right and proper I think. But I don't understand those who think science can't or shouldn't engage with objectors. I think science itself, and public knowledge generally, thrives from science being actively engaged in the wider market place of ideas.
