Everyone judges. Judging is not necessarily negative. It's a personal analysis of something that determines our own opinions of something. Judging is necessary for forming opinions, positive and negative.
So in short, yes I judge, I seldom voice my negative judgments but they are used to form my own thoughts on certain issues.
E.g. From the Rachael finch situation I guess my judgment was: not for me (negative judgment - personal) but it doesn't harm anyone so who am I to say it's a bad thing?
I would express a negative judgment in a case where I thought someone might be at risk.
