The law is always based on a society's sense of what is moral or not. It is high time our society recognized that taking advantage of someone who is incapacitated for any reason including being drunk, is not only immoral but should be illegal, whether it is relieving someone of their wallet or having sex with them because they are in no state to object.

Everyone should be clear on this rule  "if the person is clearly drunk, then abstain from doing anything that they may regret later", or you may too.
