Just go to google.com, and type in "sodium fluoride sodium lauryl sulfate", and you will get tons of similiar sites. You will find nothing justifying a positive use for the various dangerous chemicals listed. You will either get a list of ingredients from a product, a site warning you of dangerous chemicals, or a debunking site. The only debunking site i even saw was the "Urban legends" page.
I can't believe the shit we are getting. 90% of the products in my house contain poison.
