the only thing a follower of christ should do during any holiday is continue to treat others the way they want to be treated. every holiday widely recognized and celebrated is corrupt and has nothing in them to please god, if that is your goal, of course.
i personally see christmas and easter as more damaging to a persons spiritual health than halloween. at least halloween makes no bones what it is about. even poor thanksgiving has been turned into a gluttonous pigfest. it should be true thanksgiving every day!
