I think you have too much time on your hands Col old doggie. Your little difference of opinion doesn't even qualify as a storm in a teacup.
As something of a lifelong mooch, I've had the opportunity to attend a wide variety of Thanksgivings, ranging from the deeply religious to the patentedly secular. The real question is, I believe, does the immigrant from a war torn country arriving in the U.S. have less claim to being thankful than the guy who can claim distant relations on the Mayflower?
What are you talking about?
