This is low-hanging fruit, I know, but I have to point out this sort of nonsense. Halloween is not a religious event nor is it an anti-religious event. It is play-acting. Fiction. It’s like a costume party for fun. It is not an endorsement for Satanism or Wicca or anything else. It’s the same as if you had an Alice in Wonderland party. Nowhere herein is there cause for offense.
That people try to eliminate our secular holidays based on their religious beliefs offends the hell out of me.
