Well human hatred is a tough nut to crack it seems.
different branches of the same faith besides between different religions - Protestants and Catholics, Hindus and Muslims, Muslims and Christians,
I know of very few expressions of religious violence that were specifically about religion without political, class and ethnic entanglements fueling the carnage.

the UK had enough of it for long periods without going through all the other nations having such
Were the Cavaliers and the round heads really religious fighters or was is a class struggle?
Were the French and Spanish wars really over religion or over Geopolitical hegemony?

War can occur for all sorts of reasons but why is there/has been such hatred apparently between religious groups?
This is why....INTERVIEW WITH HERMANN GOERING AT NUREMBERG, APRIL 18, 1946, BY GUSTAVE GILBERT
INTERVIEWER: We got around to the subject of war again and I said that, contrary to his attitude, I did not think that the common people are very thankful for leaders who bring them war and destruction.
"Why, of course, the people don't want war," Goering shrugged. "Why should some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece. Naturally, the common people don't want war, neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship."
"There is one difference," I pointed out. "In a democracy the people have some say in the matter through their elected representatives, and in the United States only Congress can declare wars."
"Oh, that is all well and good, (Goering replies) but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them that they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country." (Italics mine)
Nothing new under the sun, indeed !
Goring was pointing out that the state has many levers to pull when motivating its people for war. Religion has been one of the most effective tools in that box.
