I don't even know what morals are. It's just a buzzword to me. We believe what we believe, and yes, some beliefs are more stupid than others. Sometimes the stupidity of beliefs is subjective, sometimes it isn't. For example, the belief that all Jews must die is obviously stupid. However, saying that the act of sticking your genitals into a rectum is 'morally' wrong, considering what the biological and social purposes of those things are, is not as obvious. A belief that that opinion is stupid is not so far fetched either, but it is not as clear a case.
