I'd like to note that, at least AT BYU (I really am skeptical about a Bishop or Stake President being able to throw you out of school, since in my last stake we had this thing called the ARP, or Addiction Recovery Program which was meant obviously to help people get over stuff like porn addictions, etc. Unless you break the school honor code in a big way, the only way the clergy can really interfere with your attending school is by refusing to sign your ecclesiastical endorsement, which would again require you to be breaking the school's honor code. The honor code is many things, but like I said before, the idea is always to warn before punishing, except in the Testing Center (or so I hear).) EVERY SYLLABUS has a little mark at the bottom telling you to come forward about any special needs you have because of such and such law so that the staff can accommodate you.
Every class does this. Be it the tiny group classes or the massive general courses, it should've come up for this guy in school.
Which means that if you have a problem being around people, you were warned before hand to tell the School, at the very least.
I mean, it isn't that there aren't bishops and stake presidents out there who are jerks. It's just that something in this story doesn't add up.
And if I may take a moment to be an uncaring, unfeeling jerk toward this person, it's kind of annoying to say "I don't care if you expel me" and then cry to the internet when you get expelled. I understand, again, that there's more to the story than this, the person may have special needs, etc, and am fully willing to recant this point, but if it were just a regular guy who said that and then got tossed out, and then cried about, I don't know that I'd feel much.
