As to the rest of your comment, you continue to peddle an ignorance as to what Halloween is, represents, its history and its very significance to avoda zora and Christianity.
Once you educate yourself on what Halloween is and represents, you’ll see the comparison between giving gifts on December 25 and giving candy on October 31. Do you give gifts on December 25 to people celebrating Christmas that aren’t religious or even Christian?
