I'm with you about Halloween generally, and especially the Trick or Treating thing with kids. Seems very strange behaviour to encourage, especially when they are also taught 'stranger danger' and to be careful of their own safety! My previous place was in a security block of flats, so I only ever had one group of kids come round (I escorted them out again, yes, mean and grumpy old me!) and my current place is tucked down a concealed driveway. But I worry about my elderly mother, though she assures me she only opens her door to the various neighbours' kids she knows.
