People will make up evidence to justify their anger.

Happens all the time.

Typically there is plenty of fighting over things known. It sounds like you are looking for a confirmation bias.

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses.[1] It is a type of cognitive bias and a systematic error of inductive reasoning. People display this bias when they gather or remember information selectively, or when they interpret it in a biased way. The effect is stronger for desired outcomes, emotionally charged issues, and for deeply entrenched-beliefs.

No. Most wars are waged over resources, others over human rights. Some may use a peoples belief in order to rally the morality of the troops, but even the Holy Crusades were not really being fought because of religious belief.

there is evidence. it's highly likely.

I do not think people need excuses to wage war.

No. Thats ridiculous.
