You've gotten lost so far up your own arse that your posts don't even make sense.Eh, halloween isn't an import, it originates in Ireland. So what you've said makes no sense whatsoever.
You can't say Halloween and Trick or Treating is something that it isn't. It's only your own fault if you're ignorant of the origins of the celebration.
The best you could say is that this is one case where integration into aspects of Irish culture has been enthusiastic and successful.
