illini07,
Thanks for reiterating that social host laws have no religious exemption.
Regarding laws allowing minors to consume alcohol for religious purposes, I believe they were originally written to allow consumption of alcohol during church religious ceremonies. These ceremonies involve consumption of _small_ quantities of wine. So it seems to me that the spirit of the law was never intended to allow consumption of the quantities required to inebriate someone.
Also, in addition to social host laws, some municipalities are starting to pass teen party laws. These laws lower the threshold for prosecution, in that adults can be held liable even if no one is injured as a result of the drinking. I didn’t mention these before because it seems that these laws are relatively new and not common. But they do signal a new awareness of the dangers of serving alcohol to minors and a willingness to prosecute this.
