Liberals and communists? Don't be silly. How many head-in-the-clouds types could even afford a baby, let alone want to go through tophet. So stop it with your cheap political digs at the opposition.
That said, I can't see any majority support anytime soon. How would it happen? It's not like we are talking about a common occurrence in the first place, and it does have the approval of the supreme sophetim. Not to mention the event is a crowd pleaser. I mean. it's not just the baby, it's the whole neighbourhood party aspect of it. I doubt people actually taste the flesh in most ceremonies. Have you ever? I admit freely, I was turned off, and I'm told it's not a pleasant experience.
So in short, how do you envision so basic a property transaction being made illegal? It deprives people of religious comfort and a reason to celebrate, it further undermines the traditional values on which, ultimately, our society rests, and I can see absolutely no reason why. Certainly, the whole 'population trap' idea was discredited decades ago, but the theory that a regular mass tophet could halt the expansion of the nations was a pipe dream anyway. Not to mention extremely cruel. Some parents, after all, are genuinely attached to their babies, and it would be quite indefensible to remove them by force.
