Mr. Ramesh Sinha, have you read The Quran? If not, pl read first and then preach. You can get category-wise verses like Absurdities, Contradictions, Hatred, Good-stuff, etc from The Bible, The Quran and The Book of Mormon at "The Skpetics Annotatetd Bible"
Pl read that and then think what would be the effect on a follower of that book who is taught from an early childhood itself that the said book is directly revealed by the "most merciful and all powerful creator"
