I don't mind it but also because it is relatively easy to ignore here in the netherlands. I'm sure i could relate better to the original post if I would be confronted to the same extent.

But yeah most if not all fun holidays are getting raped by commercialisation.
and the real history of thanksgiving, is on a par with that of columbus day. remember that little speach by wednesday in adams family values? it wasn't completely accurate, but it wasn't bullshit either. the real story was worse.
