No, I think some people are just a tad annoyed by your ATTITUDE towards it, and your self righteousness...but most people...not all, but most people can live with, "I think", you however tend to say things like "it is". Had you expressed this as an opinion, and not a matter of fact.
Actually if you read the first post there was a lot of "I" and "me" in there, which would tend to indicate that she was relating things from her perspective, her own opinion. She even opens with asking people if they agree, which you don't usually do with facts because facts are facts and not something that you look for consensus on.
