Religion is the cause of many wars or more accurately, religious people are the cause of most wars. One of the biggest religious was included the genocide to 80 million Hindus by Islamists in the name of Allah. Mughal India ~ The Biggest Holocaust in World History ... Is anyone surprised? It gets worse.
As you may know, the Muslim god, the Jewish god and the Christian god is the same vile god. He's probably pissed now because Christians are no longer killing Jews. Hitler, a devout Christian ordered other Christians to kill 6 million Jews which was around 1/2 of the Jewish population at the time. The population of Jews has yet to recover. They are now being targeted by Muslims for extermination. This is not surprising because the god of the Bible and the Koran is a homicidal maniac. What else would you expect from people who god worship a god who drowned nearly every living thing on earth and then killed his own son?
Christards will lie and tell you that Hitler was an atheist. Hitler was a hard core Christian. They will go on to lie and say that Stalin was also an atheist.
