Earlier quoted context omitted.
My point is it's not analysis. It's a completely unsubstantiated assertion of fact based on what's actually a wild guess. The info in the article isn't a study, it barely even summarises a study, and I'm willing to go out on a limb and say the commenter hasn't read the actual study. If so saying "this study isn't it" isn't simply an opinion, it's misrepresentation.
You're more than entitled to your opinion. You're not entitled to tell someone to shut up because of it.
However it quotes local officials who did do the study and have the detailed analysis saying there's a serious problem that warrants further investigation. They may be right or they may be wrong. Saying on the basis of what's here that the study is definitively bad or good isn't warranted though. That's all I'm saying.
