Explanation: One of the things that the Romans accused their worst enemies, the Carthaginians, of, was child sacrifice. Notably, this was not a common accusation leveled by the Romans, unlike being not manly enough (or conversely, eating too much meat like a b*rbarian).
However, whether that accusation of child sacrifice was true is a whole 'nother ball of wax, and you can find support in modern academia for both sides of the issue.
