Unacceptable religions

I know a guy who has come up with a test for religions he finds unacceptable. The test involves rules about clothing and appearance.  If the men and women are required to follow strict rules of dress that differ by gender, he rejects them.  He feels that morality and religiosity should have nothing to do with clothes or hair styles or veils or bonnets or underwear, and any religion that insists on those kinds of rules should be avoided.
