Jim (and I, though we don’t see eye to eye on some matters) comes from a Christian world view. That’s very black and white and does not allow a lot of room for “this person was worshiping a true God but confusedly.” From a Jewish point of view, the philosophy on such matters is a bit more liberal. I think this is where Jim is coming from.
As a Jewish Conservative (and a Conservative Jew), I see things very much as evangelical Christians do when it comes to moral and social issues. I’m less enthusiastic about the strain of anti-Mormonism that I’ve seen around here, which to me is maybe a little too close to the kind of Antisemitism that I experienced as a kid.
