I think if anyone here feels they have to stand up in the middle of a presentation (of any kind) and insultingly disrupt the person's delivery, they should contact Barack Obama........ he is looking for people like you.
I agree, I saw this happen once and it was a great lesson for all involved...there are reasons why we have instructions to follow in the Body......what I would like to know in this story is where the other church leaders were at.
My only exception is if you are the Pastor and have a guest speaking, you can and should stop them if they get into the ditch...
I had a guy try to date set "the rapture" and invited the people in our fellowship to join him...he probably felt like a rapture happened because he was out of the door in the twinkling of an eye...
