Anyone who believes in any religion that they did not create themselves is following the beliefs of others, mindlessly. Beliefs need to be justified for them to be valid. However I do not attempt to force my beliefs onto others who do not justify theirs. Instead I avoid conflict and simply internally reject their ideas as I know they hold no merit. If challenged I attempt to present my view and support it while not attacking other views in the process. Religion is a matter of belief and justification of said belief. A belief in God does not make you any less intelligent than someone who does not, even if you can not justify your belief as what counts as justified belief is a belief that can not be justified itself.
