True. In this case, it most likely did harm in the long run, but the intentions behind were good, and logical. It's not always rational to generalize, but you make a good argument. Though I'm not sure - for the most part, weird rules in religion seem to be based on public opinion as much as group identity or logic. In short: Can be good or bad depending on circumstances, no matter what it is based on.

But it's late and I'm beginning to fear for my mind. I'll stop before I embarrass myself too much.
