Why don't some people understand lack of belief?

[rskovride]

...around blissfully ignorant of a fundamental question of human existence, i.e. "Does Santa Claus exist?" It is question that demands an answer and how someone answers determines whether or not he or she is good, bad or naughty. The possible answers are yes, no, and sometimes. That's it. Everything else is just evasive puffery.

There, fixed that for ya.
