Yes, it does specifically bother me. I don't think you realize how much time and effort goes into passing a federal regulation. Meanwhile, herbal remedies are giving babies seizures.
You're letting your imagination run with this. You're bringing up completely different issues and trying to act like they should be prioritized the way you think they should because you somehow know exactly how much time and resources the FDA has to do anything. Go get some fresh air.
Is anything ever that cut and dry? It may take much more time to come to a conclusion on what you think should be regulated first. Does that mean other recommended regulations should not be made even if the research on those have been completed? It doesn't happen in this single pipeline, one thing after another. There are many different studies happening concurrently and they will finish at different times.
This was studied a long time ago. This is not new information. This is not a major health risk compared to all sorts of things that have also been studied and have not been regulated, which I have already pointed out. Why haven't they been regulated when they are demonstrably more dangerous?
