Sorry, but government institutions don't have the authority to violate your Constitutional rights. You always have a right to due process.
The no-wing situation is bullshit. All the university has to do is leave it in the hands of the responsible authority. Instead what they do is intrude on the process and then impose their own unconstitutionality process. These universities are all asking for major lawsuits from the defendants, and many of them have already been sued.
And they'll lose, because there is no right to attend a college. I'm sorry I have to keep explaining this to you.
The Path of least resistance is to throw the rapist off campus. And most places will take the Path of Least Resistance.
And it really isn't any different in the corporate world. The mere accusation of sexual harassment is usually enough to get someone fired. No hearing. No due process.
