Christianity certainly cannot lay claim to any "Moral high ground".
The history of Christianity is filled with genocide, the intentional destruction of other cultures, religions, dress and cultures. In particular Christianity has been intolerant of Jews instituting pogrom after pogrom where Jews were forcibly driven from their property, confined to proscribed areas, forced to leave a country or denied the right to work outside of particular industries.
As Christianity expanded from the Middle East it first destroyed all other existing religions and cultures in each area of expansion. When it expanded into the "New World" it continued that program destroying and banning the practice of the religions, cultures and customs of all those already living in the "New World".
In the area that became the US, Native American Children were forcibly taken from their families, forbidden to speak their language or wear their clothing, had their hair cut and were forced to adopt Christianity.
Anyone so limited that they can only spell a word one way is severely handicapped!
