Spoke with J.C., apparently those rules are "more of a guideline than a mandate".

I do question, however, that you find limitations on love perfectly acceptable - Jesus doesn't say it, Buddha didn't, certainly none of the other "great religious men" drew such distinction. I see a pattern forming there, hmm. Maybe, just maybe, you are missing the real meaning.
Such "love" is not beyond human comprehension, just practicality. For those of us in the mundane world whom can give freely and generously of ourselves without a single want of our own in this way the rest of humanity isn't too kind. Unfortunately, survival is the highest law in this case and such altruism must be tempered less one becomes a sheep in a pack of wolves.
It's thinking like this that makes such concepts unable to be executed fully, not for lack of want in the purer souls among us.
