The students should be advised and the seats should be empty. When this happens once, it will be the end to this kind of travesty. Until it happens, nothing will change. If the news were to film an auditorium with 20 students waiting to hear her, or Obama, or anyone else who openly would kill children, it would be the last time some pseudo-intellectual would invite the likes of them.
Either way, the school shouldn't have invited her, but I'm sure that program is run by statist liberals who probably think Obama is the greatest thing since sliced bread.
