There was a consensus that this discussion needed to happen, so here's a topic.
My view, directly quoting from the other discussion, is as follows:
To me, the point of SMA is to make people really think like nobles, within a context of the warring states of Middle Ages Europe. Religion should be extremely important, in many cases more important than realm affiliation. Our characters should not be socialists, should not be egalitarian, and should jealously guard their privileges. They should not be tolerant of beliefs that contradict their own, and should push their own faith. And, of course, they should not be buddy-buddy with commoners.
But over all this, I think that realities of the Battlemaster world must triumph over SMA guidelines whenever there is a conflict.
