I cannot judge the Jews who were forced into this but I look on with sadness that Jews are compelled to participate in a revolting practice simply because they have targets on their backs and need to “prove” that they are nice people. Maybe they should take off their head coverings to prove that they don’t have horns either. Sad.
There is no halloween where I live so its not a problem for me. But its one thing to discuss things with adults and its quite another with children. All the kid wants is some candy if some little kid dressed as batman or a princess comes to your house are you really going to tell him about Avodah Zarah (The kid is 6 and just wants some candy)
