Sort of. The difference is when you state an opinion as if it were a fact then you can pretty much expect to elicit a negative reaction. For example, I can't stand the Beastie Boys. They annoy the hell out of me. However, a lot of people love them and they're one of the most successful and long-lived rap groups of all time. I can say, "the Beastie Boys suck" because that's my opinion. But I've actually stated it as if it were fact, which is completely false.
