I would be very much interested in seeing any actual links to university policies which resemble your accusations.
The university policies that restrict accused's right to due process and lower the burden of proof to the lowest possible setting have been discussed at length and are not even disputed by your side.
The link entitled Vassar gives Yu's side of the story and then of course, the woman must be lying because Yu was purportedly a virgin and also the daughter of a geology professor (i.e. privileged skank). Never mind that two witnesses suggest that she appeared drunk at the time.
First of all, I am not saying that she "must be lying" (although it is likely given the evidence available to us). That you assume this means that you have internalized the "presumed guilty until proven innocent" doctrine, i.e. that you think the only way a male student accused of rape or sexual assault should avoid punishment is to prove that "the woman was lying". But the burden of proof should always be on the accuser. If it can't be proven she was assaulted, he should not be punished in any way. The only purpose proving she was lying should serve is when it comes to punishing her. If we can't prove either way nobody should be punished.
All this should be noncontroversial in a civilized society. It is very sad that many disagree with it in the name of "protecting" female students no matter whose rights get violated in the process.
Second, the girl or the college never challenged the claim that she only brought her accusation a year after the alleged incident. Why didn't she contact the police right away? Why didn't she seek medical help? If she was really raped or assaulted, why wait that long? Specifically, why wait until the very last moment to file the claim? That shows calculation.
Third, about the alleged witnesses that saw her "appear drunk". Being (or appearing) drunk doesn't mean she was unable to consent. Also, how drunk was he? Sauce of the gander should be sauce for the goose. But colleges disagree. Drunkenness, according to them, renders a female incapable to consent but it has no such effect on the male.

Furthermore, I am very skeptical of the ability of these alleged witnesses to recall who appeared drunk on a specific night a year earlier. Who are these alleged witnesses? Friends of the accuser? Was their identity disclosed to the accused? Was he able to cross-examine them? And let me repeat the most salient point, them seeing the accuser "appear drunk" in no way, shape or form proves non-consent!
Fourth, you have ignored exculpatory evidence. Rightly, there should not be any need for it given that inculpatory evidence is so sparse as to be virtually non-existent. But it further illustrates the travesty of justice Vasser committed here. To wit, the accused and the accuser were exchanging friendly messages in the year between the alleged incident and her filing the accusation. Now if she was really raped why would she continue to have voluntary and friendly contact with the accused?
Fifth, the point of her father being professor was not that she is a "privileged" (that's progresso-authoritarian language just like "micro-aggressions") but that the guy was judged by professors (i.e. her father's colleagues) after Walker requested that no students be present in the tribunal.
Which differs considerably from your claim that yes means no if a woman changes her mind the next day or year or that if both drink then he is a rapist and she is a victim. In fact, I notice what appears to be gender neutrality in the wording.
How many female students has Vasser expelled after a mutually drunken hookup? The wording might be gender neutral, but the application is very gender specific. Female accuses a male of sexual assault a year later, there is no evidence the encounter was non-consensual, male student gets expelled regardless.
Again, there is no evidence that the sex was non-consensual. None whatsoever (if there is please present it or forever hold your peace). Yet the male student was expelled.
Anyway, if I was on the jury I'd vote to give Yu Vasser's entire endowment for punitive damages. What that college did was unconscionable.
Also I think every male student unjustly expelled should file a lawsuit and force the colleges to defend their actions in actual court (as opposed to their own kangaroo variety). Last but not least this seems the only way to make the identity of the accusers public. Without the lawsuit we would not have known that the name of the girl in question is
Mary Claire Walker for example.
