Not well said. We are not talking about a subjective judgement of premises. We are talking about exposing them to objective measures, involving evidence and their explanatory potential or lack of it. I'm perfectly prepared to have any premise I ever use in argument to be mercilessly exposed to that. In fact, that's always what happens to me here and I'm over the moon about it. I can't see a single reason why any premise shouldn't be similarly scrutinised. If you don't let me apply these measures to your premises, as Joe Offer seems to suggest, then our conversation can't be an honest one, even if I'm strongly inclined to agree to with your premises. No selective, protecting veils means more honest discussion. As in "agreeing the inputs," DMcG.
