I do not disagree with the notion that just because a person believes something makes it right. However, if a community of people are to flourish then each person must be given a certain respect. This means they are allowed to put their ideas forth. This means even the minority must be given respect. If these ideas or believes are bogus or outright immoral, they will no doubt not last long in the overall picture. However, if a minority puts forth a belief that holds strong, then eventually that belief may come to shape that community. A pedophile trying to get laws to changed in order that he may do what he wants will be met with a swift beatdown. However, a reformist trying to get equal laws for a minority may be heard.
It is this notion of a democratic faith that allows for differing people to come together in a community and come to know what is right. In this way, a quality of consciousness for people can be formed. This would not result in a Nazi like society where certain peoples are erased from being a part of the community.
