Hm m m thinking more about his I think it's more the feeling that shopping for Christmas, the next holiday on the line, now intrudes so much into Thanksgiving that is has no space or time for itself. It loses meaning as it is squeezed down to not even ONE day.
I do not think shopping is evil. But I think the frenetic atmosphere that is spawned by the midnight doorbusters can sometimes bring out a lot of nastiness in shoppers.
My point is that it has always been Black FRIDAY, not THURSDAY. Let it stay in it's place and be"special" there.
