I told him that, yes, in a round about way - this is where a little research comes into play - being puritans (advocating strict religious discipline), they would not have given thanks to the Indians themselves, but rather to God for sending them the Indians to ensure their survival.
Well, other coworkers stepped in and, as usual in this day and age, I found myself in the minority in my belief - even with all the proof I had - and pretty much smiled and nodded and said, "You can revise history all you want, but the truth is there to be found if you'll search for it. But, I know you won't, so you'll go on believing what you perceive to be correct but in reality, is false."
Pretty much shut them down with that.
And this, by the way, from President Lincoln 1863:
"I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens. And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings, they do also, with humble penitence for our national perverseness and disobedience, commend to his tender care all those who have become widows, orphans, mourners or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty Hand to heal the wounds of the nation and to restore it as soon as may be consistent with the Divine purposes to the full enjoyment of peace, harmony, tranquillity and Union."
Happy Thanksgiving to you all.
