while as you say 1.5% are not lds - they are bound by the same honor code/system as the lds. So when do the expulsions begin?

At the very least, I bet those jerks who did it, and have their faces plastered all over TV, have been talked to. Bad deal on a press that jumps on any bit of negative. Kind of like this thread.
