This is becoming silly, and it seems that my question will not be answered. So I'll end my comments with these final thoughts:
If anyone feels that it is best not to proselytize on Halloween, then I respect that. No problem. What I don't respect is when people ridicule and condemn those of us who try to use Halloween as an opportunity to bring some joy, fun, and spiritual edification to children and their parents. Personally I think it is quite tacky to call endeavors to promote the Faith "tacky." So let each of us follow our consciences, and let us strive to conform our consciences to Orthodox Teaching and Christian love. I think if we all do this, then God will honor all of our actions.
