My friend the biggest example is the crusades, war is the nature of man and lets face the facts it's not gonna ever change. Now me as a Muslim dint believe that's how its should be. Islam is a religion, a Muslim is a believer in Islam, but let me remind you, like everything else Muslims grew corrupt, NOT Islam But Muslims. When the Muslims took over Spain it was not during the time of the prophet Muhammad's life. Muslims leaders became greedy and did not go by the true Muslim ways. They taxed all non-Muslims, again not something a true Muslim would do. In Islam the person has to accept the religion in their hearts or it defeats the purpose. The prophet Muhammad was very strict about that He told Muslim soldiers not to kill women and children but only but only other solders that fought. Not only that when Islam was reject by the leaders of mecca, the prophet told his followers to seek refuge with the christens of Ethiopia, because he knew that chirtanity and Islam are like to lights coming from they same source so he trusted them. so even though Muslims took over Spain in a harsh manner it wasn't the way they were truly taught

If you can find one quote from Jesus in the bible or anything else that says "I am god" or "i am gods son " then let me know. If Jesus were to come back today and you ask him if he is christen he would look at you with confusion. Jesus himself is not christian, Christianity was created 300 years after his death. Jesus had one message and it was to worship one god.
