<...Now "understand" is one word, "agree" is another and they are not mutually inclusive.

No argument here at all, but once one understands a position, if one has any moral code at all, one must be prepared to judge it. Otherwise, how can one decide to "agree" or "disagree?" How the term "judgmental" became a negative is more than I can see. I think most people use the term to indicate unreasonable and over-quick judging without possession of all the facts.

Too many people, particularly liberals, take "understanding" and try to slide it over into "excusing" without anyone noticing, and then attack those who condemn a position for not being "understanding."

I might understand why Hitler turned out the way he did, or what his twisted point of view was, but that's a long way from excusing him, and just because I understand his concept of racial purity doesn't mean I can't thoroughly condemn it.
