Honest Question: isn't Halloween a "spooky" thing?
Why is it treated like a carnival?
In EU at least where I live we have carnival for dressing as you want but Halloween is just spooky masks or accessories (or even full costume but still scary themed)
Lots o religious nuts here in the state want to make it less evil and satanic because Jebus. But also if you're a parent to small kids you don't really want to go as the psycho holding a distended disembodied still beating heart if for anything other than not wanting to have to wake up to their nightmares constantly.
