This is because of the limited knowledge that we have about other religions.
Yes, people fight over different religions as they believe their god is the one and only god, but other religions disagree with this.. causing conflict.
of course. because everybody is discriminated. wether if you are christian or Jewish or budhist. so yes, all religions should fight racism.
no religion is involved exclusively in war on terror as all religions produce terrorists because they are followed by people and terrorists are a part of people naturally. in the past, Jews terrorised the Canaan's, Christians terrorised the red Indians and south America's civilizations and Muslims now a days are the first to come to mind when talking abt terrorism though all people "and not religions because religions are thoughts" should fight terrorism.
because every person thinks his religion is right while other religions with diffrent believes is completely wrong.
The boys fight because they love the feeling it gives them. Pony is different because he does not know how to fight at all.

People fight because they like bananas in their ears.
Because they are Chinese and other nation was different than glorious China.
Everything.

Disagreements and different beliefs.
because rich people pay poor people to fight in the war because they don't want to fight in the war
