It’s true that FGM is objectively worse, and I’ve seen people conflate the two while attempting to argue that circumcision is wrong. But it looks like the commenter above focused only on the moral inconsistency of cultural mores.

If by conflation you mean using the term genital mutilation for circumcision, unfortunately that’s hard to avoid in the context of ethics when they occupy the same categorical: “is the practice of pruning children’s genitals without their consent ok or not?”
