Meaning of Freedom of Religion
I feel like I should point out to the internets out there that religious freedom isn’t a blanket excuse for doing whatever you want, neither ethically nor legally. Constitutional law has been pretty clear that religious belief is different than religious expression and in some cases, religious expression can be regulated.
And in ethics, I think it’s obvious that your ability to express your religion should stop exactly when you violate the human rights of your child.
One of those human rights is bodily integrity and freedom from unnecessary, painful, permanent alterations to your body. Ergo, circumcision is unethical and should be illegal if the purpose of the legal system is to establish justice and justice is about being ethical.
