of course, but i think it's unscientific to "support" either side, and to ignore evidence because you already believe you know the answer; scientific both precludes believing in things without evidence *and* believing what authorities tell you (without evidence)
the scientifically minded also wouldn't mind looking into the details of the controversy:
http://en.wikipedia.org/wiki/Dental_amalgam_controversye.g. when you read something there like "Dental amalgam has been found to be a frequent contributor to oral lichenoid lesions[58] and is possibly a variable associated with an increased risk of other autoimmune conditions such as multiple sclerosis, lupus, thyroiditis and eczema.[59]" -- with citations of studies -- do you dismiss such studies without reading them, or go read them before dismissing them?
the citations are:
