As I wrote last year:
We need Thanksgiving. It celebrates and refreshes our national spirit. It brings us together. And in these troubled times, when we are so viciously split by contentious issues, we need all the reminders we can get that we're one country.(Read the whole thing. It was a good post, if I say so myself.)
Sacrificing all that Thanksgiving represents for the sake of consumerism is not just crass, it's destructive to our national unity.
So again, I say to you:
If you care about the well-being of the country, not to mention your family, friends and neighbors, don't shop on Thanksgiving.
