It might be rational, but at this point it's not helpful, and might be unnecessary.
I guess that's a good point, but I do think that some people freaking out would help draw some attention to the issue.
For example, a handful of people protesting business that uses heat-reactive receipt paper might get some media attention, simply because it seems so absurd at first thought. It wouldn't stop any business from using it, but it might stop some people from handing a major source of BPA.
I think some people are freaking out already. Despite my calm exterior, I am.
Without hard science, concerns are easily dismissed when inconvenient.
For a very long time many people though of me as paranoid because I was sure that the government, and other large agencies, were compiling detailed records on everyone.
No matter how much I pushed for people to stay away from traps like club-cards, Facebook, Gmail, etc. it had no effect other than to harm my own credibility.
Not a day goes by that I don't rub their faces in it now, but it doesn't help anyone scrub their history.
The moral of the story is that nobody get's excited by a man yelling fire, they won't care until they feel the flames themselves.
So, I don't think you're wrong that we should get excited. I just don't see it achieving much, yet.
I'm glad this stuff is being talked about, but I feel like there's a bit of a disconnect in that logic. When the entire food chain has been tainted with a carcinogen that we can't even filter out of our drinking water, I'd say panic is a rational response.
