I never thought in terms of opinion vs. judgement. Usually it is opinion or fact that comes up.
I think opinion and judgement are not mutually exclusive. You can have an opinion that also is a judgement. But, I do agree with the people above that judging someone basically comes with what someone believes others should do. However, there are things I would say I believe to be a better or best way to do something and I am still fine if people don’t do it, or choose a different route. So, it is my opinion, and I think people should do it, but I don’t feel I judge them if they don’t. Their life, their choice.
