It isn’t a perfect comparison, but in both cases you’re chopping off an infant’s body part, without its consent, effectively making sex less pleasurable for the rest of its life.
I would not support a ban like this, it probably should be a family (and religious) decision, but I do argue against families making that choice.
I posted that I would rather have an exception for Jews, and to eliminate routine infant circumcision for others by social stigma rather than by law. Most circumcisions are done by Drs. for bogus "health" reasons (really to make $), not by mohels for religious reasons.
Anyway, there are Jews already questioning the use of religious circumcision. And other practices which were once absolutely central to Jewish worship, like animal sacrifices, have already been abandoned.
