Driving while intoxicated is a serious, immediate threat to the lives and safety of others, and we are right to diligently enforce its ban. Aside from that, though, the strong majority of negative consequences for drinking irresponsibly accrue to the drinker. The idea that nobody should drink because somebody will be irresponsible is extremely unpopular because nobody wants to be prejudged as irresponsible. We want to be judged by our own actions, not by the collective actions of any group we belong to, even if that group is humanity.
