Say it, and say it again when people compare Christianity's
'dark past' with Islam past and present.
The DIFFERENCE is the evil Christians did/do is AGAINST the teachings of their religion. It is a SIN.
The evil Muslims do isn't evil to their 'religion', it's sanctioned and encouraged. It's GOOD to kill all non Muslims.
You DISobey on religion to do evil.
You OBEY another to do it.
Islam is, from it's birth, a cult of death murder and terror and the only way to change that is to REVISE the Koran. But that cannot happen, because every word is HOLY LAW. Including the commands to kill and destroy.
Few want to deal with that ugly fact.
As Christianity is practiced now, intolerance as evil. When Pope Paul IV was ordering the burning the Talmud, that was good, as defined at the time.
At about the same time as Paul IV, the Ottoman Emperor, Sulieman the Magnificent -- known as "The Lawgiver" in the Muslim world -- was welcoming Jewish refugees and rebuilding the walls of Jerusalem and opening it to all religions.
Such were the religions, as interpreted by their leaders, at that time. Is it no wonder Islam was ascendant at the time?
Now it's generally reversed, granted. I'm not going to call Islam a religion of peace -- I don't think any religion deserves that title. But, better than condemning Islam out of hand, hold up Sulieman as a model (at least for rulership, if not for family life) -- Look how great the Islamic world was, when its leaders tolerated all religions. Look how weak it is, now that it hews to narrow intolerance.
