“I do not understand the basis for the question. Frum jews with emunas Hashem should celebrate each and every day as Thanksgiving. Is not the very first thing a Gd fearing Jew does every morning is to recite Modeh Ani?????”
So in other words, of course its muttar to celebrate Thanksgiving!
I agree completely! though I think having a turkey everyday might be a bit much . Plus getting together with family that may live out of town isnt super practical everyday
