Has anyone been disciplined in any way for going to college?
The only formal discipline is the (potential) removal of "special privileges" (being an elder, MS, pioneer) if you or someone in your family attends a university.
However, there is the "informal discipline" that will almost certainly arise - whispered behind-the-back comments, gossip, repeated "shepherding visits" (thinly veiled pressure & criticism), loss of social acceptance by the group, etc.
Each congregation has a "flavor" if you will - some are far more conservative than others.
And of course some individuals / families are far more sensitive to the "informal discipline" than others.
If you have a strictly conservative congregation and a sensitive family - it can lead down a very bad road.
All that said, of course, does not in any way, even remotely, justify horrible actions.
I.e., it can lead to understanding, not justification, of the situation.
