Thank goodness many of the comments seem sensible. So far.
IMO their comparison to being raised Amish and being circumcised is a poor one. There's no "birthright" religion, and even someone who initially drops out after 8th grade can always go back and get a diploma or GED later on, and eventually go on to college if he/she wants to (sure the ex-Amish young adult would be a few years behind, but ultimately can catch up and having experience as Amish may even be a plus in a few cases). Circumcision is robbing someone of their birthright - important tissue that one was born with - and like most medical amputations can never be fully reversed.
ETA: I figured out a good analogy to compare the two situations - being sentenced to life in prison vs. being executed for a crime you did not commit. The former can be undone, the latter cannot.
