Blanket punishment for everyone is just abuse. Why should fraternities that don't host drug-fueled gangbangs be punished with those that do? Imagine if they said "all parties hosted by black students" or "all parties hosted by LGBTQ students" instead of fraternity parties; there would be riots.
The Left has always hated the Greek system because it is something outside of their power structure and is all male or all female. They despise that. They forced the Boy Scouts of America to accept girls and now they are going after fraternities.
For the record I was in a Catholic fraternity in college (Alpha Delta Gamma) and while we had some pretty drunken parties we never once came close to what this frat at Cornell did, but I am sure they were an outlier.
Of course the University lacks authority off campus and so the frat could host parties off campus, but even then, knowing the way Liberals think, they will probably kick students out of school for even doing something off-campus. It's how they roll.
And the girl was NOT a member of the frat so why are the boys punished when the girl was an eager and willing partner in a drug-fueled gangbang?
You punish the guilty, not anybody you think could maybe be guilty of something some day. America has innocent until proven guilty; the Left is always pounding on that. Well, the rule, which appears nowhere in the Constitution, doesn't really apply here but the Left would certainly make the claim if the roles were reversed. So why are all these kids being assumed guilty without charge?
Dean Wormer would get it. Even HE didn't kick the other fraternities off campus in Animal House.
