first, when you LOL too much, it betrays an inherent insecurity and the fact that you cannot be reasoned with.

Saying indians were descended from former slaves is like saying that chinese are descended from chinese female slaves and japanese soldiers, mogols, etc. which i am sure u r given your inherent insecurity.
As for me, i am from kerala christian, which makes me a mix of tamil(50%), roman, greek, arab, european and jewish
