don’t fucking mutilate your children is the best argument I’ve heard

There's no non religious argument for it. Why stop at the dick skin? There's other pieces you could remove without causing too much damage. Aesthetic surgery for infants is weird

I wonder what is the argument for it?

It's mutilation. That's a pretty big argument against it. It probably made sense thousands of years ago in the desert, without water to wash it. Having been at the beach, I can attest that sand can get in there. I could imagine that being uncomfortable in the desert. Most people don't live in the desert. In most countries, you have water... I see most of those rules from the Old Testament as hygiene rules that made sense way back when. For example, pork needs to be heated to a certain degree to kill some parasites. If you don't know that or can't cook it properly, I could see someone saying "let's just drop pork". But we know better now, so we can enjoy bacon. I don't think an old man in the sky will be pissed off that I had bacon. I think it's all humans trying to make it as best as they could under their own circumstances at the time. The problem is when people take that out of context and still do it, when none of the original reasons apply.
