Arcady: it can't be a false opinion. I assure you, it actually is my opinion. If I were pretending that it were my opinion when it isn't, then it would be a false opinion.
We could argue all day about whether or not my opinion is based on fact...I base it on issues like the Peter David/Bill Jemas catfight, the firing of Mark Waid off of FF because he didn't want to alter his popular, well-written storyline due to editorial pressure to make it more like the proposed movie, things like that...but whether or not you agree with my opinion, that doesn't make it any less my opinion.
