This seems to me like the scientists working for Philip Morris insisting that cigarettes were safe for decades. I really don't know how concerned I should be about BPA, but the fact that it was initially developed as an estrogen replacement leads me to believe that it must be bioactive and thus I should be concerned. I just bought more BPA laden Tupperware though so I can't be too concerned (American Tupperware has gone mostly BPA free, but they haven't felt the need to make the same changes outside North America. Also my understanding is that the BPA replacement chemicals are just as much wild cards as BPA so BPA free might not be a good answer either) I do hate when these issues become political though because it becomes harder to separate the science from the propaganda.
Here is another perspective from Yale 360:
