Circumcision is a minor surgical procedure, yes.
I do not think it should be illegal, but I do not think routine infant circumcision is a good practice. The foreskin does have a function, and while its removal is not tantamount to removing the clitoris (one can dislike male circumcision without equating it with FGM; the latter is far more invasive and damaging), I am not a fan of removing a part of a person’s genitalia without their consent. The reasons often provided for doing so, “it’s easier to clean”, “women prefer it”, “he should look like his father” are flimsy at best.
Circumcision later in life due to phimosis is only done in the severest of cases and it is rare. My foreskin is naturally tight, tighter than average, but it has never presented any sexual problems for me, and I would not have opted for circumcision if I’d had the choice.
