Any non-circumcised male could choose to undergo the process as adults, I don't hear of many takers.

Serious question: how far should that be allowed to go? What if someone believes cutting off their child's earlobe is best for their child (for the sake of an example)?
As I see it, religious freedom does not mean you get to do whatever you want with no comeback.
While I find the idea of cutting off the earlobe repulsive, I don't think it sufficiently crosses the line of harm. For all I know this could be a legitimate practice by some obscure tribe.
Finally, no one says religious freedom means you can do whatever the hell you want without any repercussions. That's a gross mischaracterization of it.
Stockholm syndrome is very likely in those cases.
