Banning male circumcision is as anti-semitic or anti-muslim as banning FGM is anti-christian (yes, FGM is a primarily christian faith driven activity).
If people wish to celebrate their Jewish/Muslim/Christian heritage by lopping off bits off of genitals, then they are perfect free to do so in my book, just as long as the genitals in question are their own, and they are considered mentally competent to consent to the process.
