The comic answer to the Santa Claus thing is 'yes, ban the old git'

But the serious answer is, hang on a minute, no-one has mentioned banning anything. No one has mentioned, or even hinted at anytime of action or discrimination against people's beliefs. merely some of us have said that our belief in the 'wrongness' of their belief (or on the wider level - our belief in no belief) is as equally valid as their belief in something.

The trouble is, that by arguing very seriously, strongly and passionately against something, your point of view often gets taken less seriously (as if you are merely spoiling their ideas for fun) especially when your belief is a lack of belief, which is never going to be as sexy as believe in an idol / a book of writings / a set of beliefs etc.
