I agree with you on the monarchy, and I'm an atheist as well, and I still can't help but read your comment as divisive and distracting from your earlier argument for a sarcastic barb at the bible.

You haven't even argued against the metaphor at all, you've only stated you think the bible is illogical. For what it's worth there are secular equivalents of this sort of risk analysis metaphor; the bird in the hand, a stitch in time, one today is worth two tomorrows, etc.

How?

We've more or less gotten rid of royalty, and now we have celebrities shamelessly shilling just about anything - what an improvement! I would prefer neither, but I don't think that's ever going to happen without people being forced to take responsibility for themselves.
