No.....Opinions differ from people to people......And, people tend to put forward their opinions, and they'd get a lot of disagreements, and an argument would get started......This is normal human tendency......
I don't really agree with the image, because if we don't express our opinions, it's like we're not even living. I mean, if we didn't discuss about anime and didn't have disagreements about various ideas, forums like this one would not even exist.
