"You really want people to conduct a "Traditional Latin Mass" on Thanksgiving? Is this before or after the turkey?"
No more than you want them to dress up like Puritans and invite over their Indian neighbors for venison. The point of the original post was to raise awareness of an earlier historical date for the "first Thanksgiving". Mine was merely to show that the concept of "Thanksgiving" has even earlier historical roots. Of course, if you want to assist at a Traditional Latin Mass on Thanksgiving or any other time, I would encourage you to do so.
I don't believe the puritans were aware of what some Spanish settlers had done. By the way, it was the English who settled America, not the Spanish. I bet if we look hard, we can find some French as well as Dutch celebrations in America that we can imitate.
No one praises the Puritans for being anti-Catholic. Absolutely not. That's not why the holiday was started.
