I agree with you that forums are not exactly a clear picture of living in USA, but they are showing that Americans have no clue about Europe
"Troy" comment - I think au1929 posted it from some newspapers (I mean, it was surely from some papers - story about 16 year old girl watching "Troy" by herself and how terrible it is - I am just not sure if it was au1929 that posted it but I think it was) - but USA is not alone in it of course - in Australia they rated Harry Potter "R" at the beginning, later they changed it.
By the way, although it is a bit affection of personal freedom I have no problems with ratings, I just think that sometimes it's going to extreme. I really don't know why even 12 year old kid shouldn't see Troy, but, okay, I am not saying that my views should be accepted generally
And you don't need to apologize - one of problems with written opinions are that they often sound more harsh or more offensive then they actually are - you don't see expressions, you can't hear a tone of voice, etc... mine are not exceptions
