This whole notion that being non-judgemental is some sort of value to aspire to is seriously misguided.  We all judge ourselves and others all the time.  Doing so is not only natural and unavoidable it's the only way our values and morality mean anything in life beyond empty and worthless sentiment.  No, judgement's good and necessary, no doubt about it.

The only problem with judgement is when it's rash, hypocritical or otherwise unfair.  We're going to judge each other anyways, we just have to do so properly.  In this case, as former premies, we're generally so thoroughly familiar with the issues and various interests and beliefs people have, especially old friends, there's little threat that we'll judge premies without really understanding how or why they're defending their cult leader as they do.  In fact, their thinking, such as it is, is often painfully obvious. We know exactly where they're coming from and we're entirely qualified to judge them accordingly. 

Now, of course it's always possible to avoid delicate subjects amongst friends but, let's face it, a friendship that needs those kinds of taboos is already seriously compromised.  Real friends trust one another and trust one another's reasoning at least enough to have honest, frank discussions about things that matter.
