Just as long as they are snooping into ALL the students lives and are expelling the ones who are drinking, swearing, having "normal sex" eating too much or committing any other "sin".
Most people that committing "other sins" don't try to convince others that their sin is acceptable. It is obvious that these students drew attention to themselves and are testing the waters.
Very much doubt it... Since they aren't morally pure themselves, they shouldn't be judging others' behavior. Expulsion and other serious punishments should be for drug/ alcohol offenses, fighting, and other serious offenses, not students' sex lives.
That's the difference. Christians generally understand human weakness. "We have all sinned and come short of the glory of God." And we are excited when sinners (a group that includes all of us) repent and turn from their wicked ways.
But to try to force the Church to accept sin and to declare it respectable is intolerable.
