That's not true at all.
Halloween is quite fun.
Being able to go to Fall Festival's ( carnival type parties thrown usually by churches), Fairs, Halloween costume parties, getting to dress up in spooky, silly, ect. costumes, trick or treating for the kids, ect, decorating your yard with spooky stuff to entice and scare the kiddies, carving pumkins, going on Hayrides with your friends, corn mazes...the list goes on and on of activities to do during Halloween time.
No one really (well not normal folks anyways lol) celebrate it for evil reasons..it's just like Christmas..it's just another reason to get together with friends and be silly and have fun.
