Actually i find that its just people having some belief trying to prove people of some other belief wrong ...and to tell you the truth infact we can say the naked truth.....most of these people no matter how much they study and research will not be able to find the actual happenings of the past.....so please stop blaming some belief to degrade it, and never is a whole community responsible for the acts of some particular individual of the same community...so just relax and forget raising issues from the past which hurt humans and humanity in particular.
