'Impermissible' Thanksgiving

According to this site and Mufti Ebrahim Desai of the Fatwa Department:

Thanksgiving being a national holiday express its salient position in the American culture, which has many unislamic values and principles. Celebrating Thanksgiving purposefully or subordinately is an expression of accepting the general American Culture. It is not celebrated independent of the American Culture. In view of the above it is not permissible to celebrate Thanksgiving Day.

To all my readers who are otherwise inclined - Happy Thanksgiving!!
