Ligthen up a little a little people, if you're going to throw away halloween for it's pagan background, then you should also throw away almost all customs of the other holidays you celebrate.
including: christmas, and easter.
the christmas tree, the easter bunny, eggs, etc etc are all pagan things.
but, as we all know they don't hold the same meaning today, as they did when they were invented.
(ps. the church tends to steal a lot of concepts from other religions)
if for one night, kids dress up as ghosts and go door to door for candy, what harm is there in that?
it's not a pagan ritual, it's kids having fun.
in short: stop stroking your ego, get off your moral high horse, and eat some freaking candy
