You made what you thought was the best decision for your son. My wife and I made the opposite decision for our sons believing that was in their best interests. The decision you made on behalf of your son is none of my business nor is the decision we made on behalf of our sons any of your business. Certainly, the government has no right to insert itself into the decision.
Frankly, I think that both sides on this debate greatly exaggerate their medical positions. Both sides greatly overstate the consequences of the decision on a minor medical procedure. I'm amazed how emotional some people get over this issue.
I don't think that male circumcision is a big deal, one way or the other. I do think that the issue of mandatory compliance (either way) is a big deal and all freedom-loving people should oppose.
What about female circumcision?
