Everybody has a collection of beliefs; however, what differentiates people is the quality of their beliefs and the strength and determination they show in keeping those beliefs from substantial change.

That statement is False.

What differentiate people is not the quality of the people but how much control the people let their belief control their behavior.

Some people let their belief to give them justification to show prejudice toward people who held different belief while the others can acknowledge that other people might have different belief and tolerate those differences.
