"I celebrated Thanksgiving in an old-fashioned way. I invited everyone in my neighborhood to my house, we had an enormous feast, and then I killed them and took their land." —Jon Stewart
This is the day Americans celebrate the Wampanoags saving their ass. Given what our leaders did afterward, Ethnic Cleansing Day, Racism Day, and Imperialism Day all cover US policy toward the continent's First Peoples. Or, given Jesus's comments about people who make a show of their goodness, Hypocrisy Day works just fine.
If you want to imagine what was lost, I'll repeat an old recommendation: read 1491.
The saddest thing about Thanksgiving Day is it's a celebration of what rich people stole. The best that poor folks of any hue can hope for is a free meal from a civic group—not exactly a fair trade.
Which reminds me of what David Stemple would tell his kids when they complained about fairness: "In a fair world, you would be starving in a hut in Africa."
Though there is plenty of food in the world for everyone, today, in the US, millions of people are malnourished and hungry, and in the world, every 3.6 seconds, someone will die from hunger.
Well, that's enough reality for 24 hours. Our Thanksgiving will consist of eating too much great food with good folks. I wish everyone's would.
