For those who haven't read it yet or for those who are interested, here's a link to my 2010 article on Thanksgiving.
As is usually the case, I approach these questions in a different manner. I'm not binding your conscience, nor do I want to ruin your day but it's interesting to observe the responses I get when I tell people I couldn't care less about the American holiday of Thanksgiving. This year will be no different, it's just another Thursday and I'll most likely be at work.
Being counter-cultural in this case is viewed as being somehow anti-Christian. To me it just further exemplifies the confusion in most people's minds regarding these issues of Kingdom, culture, and state.
I realize virtually no one will accept my argument. I realize very few will accept my arguments in general. But as always, it's something to ponder and meditate on.
