A critique of conservative stances on morality, or religious stances are that they are restrictions forced onto people by those who refuse to accept their differences. A preacher with homosexual feelings will adamantly obsess over the passages in the Bible that claim homosexuality to be wrong because it valorizes his work of suppressing and sublimating his feelings into God. But this is a subjective view. Sublimating lust into God is difficult and is part of an ascetic life. In our corrupt society, it's difficult for those who struggle with lust because they are bombarded with porn, softcore porn, child pornification, basically there is sex and lust everywhere one looks. In the end, it doesn't really matter how people see this 'theory of moral restrictions' because their view is subjective. A subjective view of a subjective view is pretty weak and useless when we are on a quest toward finding an objective morality.
