I don't doubt anything you say, and I'm so sorry that person close to you had to go through what she did.
Is it weird that in cases like Nassar or the Catholic Church scandal, I end up feeling angrier toward the people who ignored/covered up the abuse than toward the abusers themselves? It's not a totally rational thing, but I think if I had to explain it, it would be this: Pedophiles like Nassar, Sandusky and the priests are just straight up evil. I don't know why they are that way, and I don't care. Evil gonna evil. But the people who covered up for them aren't evil. They are presumably well-meaning people in positions of power who should be as horrified as anyone else by sexual abuse. As best as I can tell, their biggest fault is their narrow-mindedness. They're so focused on other concerns (like protecting their institutions) that they completely ignore the humanity of the victims.
The MSU case angers me the most of all because they can't use the excuse of "This was a different time" or "We had heard things but we didn't know for sure." This is all happening now, in real time. Not only have all of Nassar's horrific abuses come to light, but there are a million other examples of institutions -- even other universities -- that handled these cases poorly and suffered as a result. Even if his only concern were MSU's reputation, you'd think Engler would know to at least pretend to care about the victims and not keep saying (and doing) dumb s##t.
Maybe that's what it comes down to. Evil doesn't bother me as much as flawed human beings who should -- but are continually unable to -- do the right thing.
