I guess we disagree on two points:
a) you implied that christian male circumcision is a religious thing, which it is not
b) you believe that male circumcision is a mutilation, which it is not
Females more or less get their sexual organs, at least the part around the vagina, removed, that is a mutilation, sexual intercourse afterwards is a pain and not fulfilling. Males only get a bit of skin removed, sexual intercourse an a normal sex life is no problem.
However if you like to fight for male rights not to be circumcised, go ahead
