this, cristianity was out of controll 300-400 years ago.
the most basic in Christianity is living like Jesus Christ lived, as close as you can at least since none of us will ever be perfect
so it wasn't Christianity really, but some evil men that took advantage of the church's influence to ensure they remain in control of everything by force
with Islam it's a very different story, Mohammed being the highest human in the faith was a warlord
"Muhammad attacked other groups as well. In 629, Muslims attacked a Jewish settlement in the oasis of Khaybar in Northwestern Arabia. Shortly after the conquest of Mecca, Muhammad received Surah 9:29, which ordered Muslims to fight non-Muslims (including Christians and Jews) until they submit to Islam"
check the faith map in Africa and the Middle East, where Islam rules no other faith survives, but southern Africa for example is Christian mainly with many other smaller faiths
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
