My perspective:The only possible reason you might not want the genital mutation of females banned would be that it would (if I am understanding right and you mean the removal of the eggs/uterus entirely) be a 100% sure in-fertilization. But the reasoning there wouldn't be valid, as humans currently number 7-8 some Billion people. So there would be no need. Not what it is. They remove only the external parts (like the clitoris) so you can sill conceive. Sex just doesn't have all the pleasant sensations it might otherwise, and might be terribly painful, depending.
And as far as both of them are concerned, I do have a problem with the fact that circumcisions are performed at birth, often or no reason. Around here, at least (the US) it's basically the done thing when you give birth to a boy. It's not technically required but many doctors will pressure and push for it, based on the fact that it's long-standing standard practice. And many of the people who say yes to inflicting such on infants too young to even understand what's being done to them, much less to agree with it, don't even have religion as an excuse.
Getting into the religion argument opens up an entirely bigger can of worms though. I think I'll see where this goes and wait for some actual adherents of the religions involved to give their opinions before wading back in.
