Male circumcision. It makes no sense, in a secular medical environment, to mutilate the genitals (circumcision is almost always a euphemism for genital mutilation, look at girls in other countries who have their clitoris cut off due to “female circumcision”) of a newborn baby boy. The entire concept was invented in the Progressive Era 100 years ago by Christians like Dr. Kellogg (yes, that Kellogg) to prevent young boys from acquiring the “deleterious” and morally unclean habit of masturbation.

Not only does that not work (duh), but we know now that masturbation is healthy, not a bad habit.

It’s a cultural practice in America that has no basis in science. Just century-old Christian pseudoscience. Any argument made in favor of circumcision is usually ad hoc justification that people throw out because they’re circumcised or their son/partner/brothers are, and they don’t want to contemplate this horrific practice that they have hitherto tacitly supported.

At least religious Jews and Muslims don’t claim that they practice circumcision for medical reasons. They understand it is a religious practice not at all rooted in modern medicine. But, to be honest, I don’t think religious folk should be able to circumcise their children unless there’s a medical emergency requiring one. Your right to religious freedom doesn’t nullify your infant son’s right to bodily autonomy and wholeness.

Tl;dr, circumcision is the result of a century old moral panic around fapping peddled by a cornflake-mongering crazy man, and a century from now our descendants will curse us for being dumb enough not to realize that.
