It means it wasn't based in christianity. But is this so wrong? Memorial day is not based in christianity, neither is saint valentine's day. Yes, I'm serious, before saint valentine existed, this day was known as "Feast of Lupercus", and had many similar traditions to valentine's day. It is only called valentine's day today because the church decided it needed to make all pegan religions christianized. Halloween was chrsitianized long ago by the church as "all souls day", even if that name for it didn't really catch on as much as "all hallow's eve". And besides, I'm atheist with christian heritage, so I still celebrate christmas as a day of family togetherness. Tradition is a good reason to celebrate holidays.
It's a national tradition. God forbid you have to spend one night out of your year giving kids 10 dollars worth of candy. If you can't take it, just put a few paper bowls out front and fill it with candy, and put a sign that says "hey kids, this is all the candy we have, make it last, bitches"
Or you could make a sign on a table that says "all candy is on a table to the right."
And on that table it would say "all candy is on the table to the left"
but both tables would have nothing on them.
Good luck with not getting toliet papered though.
