Very well, I'll say it - Option 2. I've never seen an argument against this that isn't just "KNIVES ARE REALLY SCARY!!!!!!!!!!!!!!!!!11111"or something similar.
It sounds like you're conflating this with arguments against male circumcision, if unintentionally.
Male circumcision is harmless if unnecessary, and both it's advocates and opponents have nothing but opinion on merits to back them up
Cutting off the clitoris, often *specifically* so that someone cannot feel sexual pleasure in the future, is horrifying. I do not consider myself a third wave feminist, so I'll avoid the intersectional argument, but I can't think of anything more "patriarchy" than mutilating women so that their vaginas are only good for babymaking. Also, it apparently makes sex painful to the point of excruciation
