i tinks its depends on who you are and where you are...westerners typically defined by the Christianity common thread had a very significant contribution by the the Great Brits in 1260? called the Magna Carta which became the basis for most rights law amongst the colonies. Concepts, wording, phraseology and are of English heritage.
Our heritage with respect to liberty, rights, freedom and democracy are creatures of the British political and philosophical thought, thus Muslims/ africans/chinese never saw nor participated in that thought. We all evolved differently.
The Founding Generation would attribute the roots of their political and philosophical heritage as equally emanating from their Judeo-Christian tradition.
