Need help/a response to someone who is convincing others Iodine is bad, when I am trying to spread how good it is.

So I am trying to show how iodine is actually a good thing to some sick people.

One person though is really making it difficult as they won't be convinced and are also convincing the others the iodine is no good, because they dont know any better.

SO heres a response I received from him, of which I need to give an answer too that will help, but I dont know the science in and out, all I know is that I'm feeling better than I have in a while thanks to Iodine.

"This short video [preceded by an even shorter commercial] shows how too much iodine can create too much thyroid hormone, and create a condition of "hyperthyroidism". The thyroid gland is the ONLY organ of the body that can absorb iodine. One hundred percent of the iodine that you take goes DIRECTLY to your thyroid gland.
