didn't say it was practical or achievable, unfortunately
I agree with you, it is a shame.
I know the feeling, it's one of the reasons why people like Fred Phelps, Abu Hamza and Richard Dawkins annoy me so much. Extremists unable or unwilling to ever consider that they could be wrong, or to understand the sheer amount of assumption and belief underpinning their views...
This seems to be true across a whole range of beliefs, whether they be based on Religion, Politics, Nationalism or whatever. This is why we never seem to actually advance beyond divisive, boundary driven ideology as a race.
