Circumcision is not mentioned in the Koran. It is a requirement in the Torah for Jews.
Muslims are required to be circumcised at age 13 - even if it isn’t mentioned in the Qur’an.
Muslims have circumcision of males performed as well. The big thing is that having a sex-change operation is far worse than a child getting circumcised, and readily condoned by society. The latter has been done for thousands of years with very little problem. I personally would oppose this bill solely for it making little to no sense whatsoever. If you condone a man getting his privates mutilated and rearranged to resemble a woman, why should you care about some male child getting circumcised? Absolutely not at all.
If a Muslim becomes apostate enough to reject part of their scripture, then that might fly.
However, fundamentalist Islam as practiced for over a thousand years has both a greater and lessor set of scripture. The Koran and The Hadith.
Circumcision is in The Hadith.
