This is something I often think about - especially when I'm on these forums - as it often results in debates becoming arguments. And I'm guessing that most people's gut reaction to the question will be, "no, of course they can't."
"Well that's just my opinion," seems to have become a get-out-of-jail-free-card for anyone from racists to the mythical beings that say they don't like Mafia (it's OK my friends, they're not real). In some cases that's a perfectly valid response when talking about an opinion on something subjective (a film/game/book, etc.) but in other instances that doesn't work.
If I said I hate Australia because they invaded China, then my opinion is wrong; that never happened (at least, I don't think it did...) and so my opinion is based on a false fact which in turn makes my opinion wrong.
So to me, an opinion can easily be wrong - of course, that's just my opinion.
Does anyone agree or disagree?
EDIT: This has come up quite a few times now, and I think that a far better word to use is "invalid" as opposed to "wrong".
There's a difference between fact and opinion.
Facts are statement that can be proven and opinions are ones that cannot be proven by scientifically, statiscially, etc. means. They're based on someone's thoughts, their feelings, and their understanding.
Stating "I hate Australia" is an opinion.
Stating that they invaded China is contradicting a given fact.
Anyone who says the sky is red is just dumb.
