I was raised in a Christian home and my parents allowed my sister and I to go out and trick or treat. They let us make our own decisions about it and wether it was an "evil" holiday. The holiday itself is not evil if you just let kids dress up and go around trick or treating. Hell as a kid my parents encouraged me to go as part of the "thearpy" for my stutter, it got me out and interacting with nore people. Though I have to say if I had kids now I don't think I would let them go, there are to many wackos out there, when I was a kid the worse you had to worry about was some older kid stealing your bag.
