Apologies if this has been done to death already but I don't think we've debated this for a while. In the UK, homosexual practice between men was illegal until 1967 (don't know about the US); would posters here suppost criminalisation? If so, why? If so, would you also support the criminalisation of other behaviour which you find morally objectionable such as and sex outside of marriage? I would not support criminalisation. First up, there is an important distinction between what one might consider illegal and immoral. For example adultery and sex outside marriage are considered immoral (under "traditional morality") but are not illegal. To criminalise one violation of "traditional" morality, but not others is rather inconsistent. Second, there is the obvious issue of enforcement. Regulating people's private lives is difficult to police and creates obvious problems. Malicious complaints could be made against people- either those which were false but used as a threat; or to blackmail individuals. Over to you!
