My understanding is that the far left is anti-circumcision.

More to do with anti-unnecessary-medical-procedures-with-no-benefit-yet-lifelong-consequences-performed-on-infants-without-consent.

It’s a question of body autonomy rather than circumcision as a practice unto itself; obviously, it’s medically necessary for many people later in life.

My understanding is circumcision is just seen as the ‘done thing’ in the US whereas it’s not as common elsewhere. Certainly not as common in New Zealand.
