What statement or statements that appear on that site are not true?
The site seems to be aimed at adults rather than neonatal circumcision which for me, removes the objection of permanently modifying the body of someone too young to know or understand what is happening. The emphasis seems to be on the cosmetic quality of the outcome even if circumcision is indicated for a non-cosmetic reason, though I see it as also promoting it to a limited degree as a purely cosmetic procedure.
What is notably absent are spurious health claims about circumcising someone who does not already have a problem with his penis. As such I think adults can read the site and decide, hopefully after doing a bit of independent research too, whether they wish to take up this man's services or not.
