From my understanding she feels that the mechanisms for these endocrine disrupters are there, that they act similarly to BPA, which is better understood, and that over time as research is done we will find more ways that they interact. The research is hard to do and takes a very long time, and quite a lot of it is not definitive because it is difficult with so many confounding factors, but there is a lot of it and more over time.
(I also avoid these things but only because I feel paranoid about it.)
