One important point about mercury is that it stresses your entire body so it will never just cause one or even a few illnesses, it will just stress your entire system until your weakest link (which is usually determined by genetics) breaks. Its the most destructive non-radioactive element there is, not something that can passively be stored in a human body and not cause any damage.

Also, It is documented that the Germans used fluoride on the Jewish people in the concentration camps, and now it is in water nearly across the whole united states. How can you not get suspicious when you come across things like these?

You would have to be an idiot to think that these scientists could just ignore the plethora of information about the dangers of mercury and fluoride and just move ahead like this was not going to hurt anybody. Who knows exactly what is really going on, but its certainly suspicious. Are the people who see these connections the crazy ones?
