The point I'm making here is that, well, for all your comments about RBSD, nothing you've posted shows any actual understanding of what it actually is… which is why I've been asking you to clarify what you believe it to be… I mean, you gave a poster child for idiocy, who's nothing to do with RBSD, as an example… because it was the "easiest one you could find"… if it's not actually an example of what you're trying to demonstrate, then it's not the easiest you could find… as it's not what you were looking for.
