Oh, if you assert that opinions are beliefs in things that aren't provable or have yet to be proven, sure, they can be wrong. I just think some of the examples people are using to say "Opinions can be wrong" are a bit misleading because they are not actually opinions. They're a denial of facts as we know them.
I don't think I ever asserted that I didn't think opinions can be wrong. Not ALL of them can be wrong though because some of them are merely personal preference. However, some people are saying "Michael Jordan is a bad basketball player" is an example of an opinion being wrong, but you can use statistics to prove that he was one of the best. I think that's an instance where you can say that is factually wrong. You can argue about whether he's the best ever or not and neither will be wrong, but I think you can say someone is factually wrong if they try to argue he's a bad basketball player because statistics prove otherwise. I suppose some people can say you can't use statistics to "prove" something like that since statistics are often misleading, but that's neither here nor there.
So really, all these arguments are a result of the fact that not everyone here holds the same definition of what an opinion actually is.
