Intolerance...do you agree with this or not? your opinion it's all?

we were talking about intolerance and all of the wars that happened through out history.and basically it all came down to one thing.selfishness empowered by intolerance.the catholics and the protestants, blacks and whites and whomeever, iraq and the us, christianity and islam..someone in the cl said that well the wars were necessary because unity is better than nothing.i said forced unity is NOT considered unity but a sort slavery for whatever the intolerance was.someone else said that yes they should have a war to defend themselves for the opprsssors.it all came down to what should we do to get rid of intolerance.someoe said love, the other said through war.when the teacher came to me.i said i would go in every single person's house from where i live to the end of the world, make sure i get everys sngle person and just shot them.once everyone is dead and i'm the only one alive there woulndt be any more intolerance.like who else can i intolerate? myself? ur opinion? what would u do
