In my opinion, the "community" (generally speaking) is "behind" looking into environmental triggers. I can go to autism websites all over the place and get links to studies involving autoimmune triggers, possible environmental concerns, links between autoimmune diseases (type 1 d included) and autism, etc. etc... Very little of that is relayed via type 1 diabetes websites, forums, etc... You rarely see it, whereas it's common knowledge in other "communities". Unless (which may very well be the case), I just haven't found the right type 1 diabetes forum or group to discuss these topics without be calling a tin foil hat wearing freak.
