I think it is very important to distinguish between judging the person and the act.

I will do my utmost not to judge the person, which does not preclude acknowledging whether or not I enjoy their company; and if I have discover that I am holding someone in judgment then I will actively release them from it. I do however consider it unwise not judge behaviour or attitudes or standards or beliefs, because to not do so means that we consider everything to be acceptable, and that is the top of a very slippery slope.
