A smart-alec Border Collie who 'thinks' he can even harass a bunch of goats into doing almost what he wants...

and yeah, Kevin...a good distinction....now we can argue over where the line should be drawn. But it is certainly true that we never learn the relevance of our own beliefs without at least seeing how others see them...and hopefully, why they see things differently. If you cannot clearly argue the opposite viewpoint, you cannot truly defend your own.
