Actually, it's predictable that you would just do a Google Search and link to the first thing you saw without reading it, looking into who wrote it or examining methodology.

The researcher you cited has an anti-circumcision Website. He accounts for his lack of hard data on this question with the acknowledgment "There is reason to believe that many deaths from circumcision are attributed to other causes." Oddly enough he doesn't actually cite a number there. Nor does he cite how one could try to estimate such instances in spite of that data gap.

Bottom line is doing a Google search and finding a kook does not mean you've presented meaningful data. You need to stop believing everything you see on a Website with a nice layout.
