An opinion by it's very nature is a judgment.
I have nothing against judgments or opinions. But I will say one thing, I don't agree with the idea that everyone is entitled to their opinion. I do believe that everyone is entitled to an informed opinion, however. We run into trouble when opinions are offered about another person's experience, because more often than not, it's waaaay less than informed. When those experiences in question start to delve into larger ethical questions, or when those experiences have a tangible effect on others around the, then informed opinions can often be appropriate.
