I disagree with this bolded premise entirely. Denying the existence of a problem absolutely allows it to grow. Ignoring a problem or denying that it exists often, (if not always) makes the problem worse. I'm also not sure Senethro suggested what you say either. It actually seems like Senethro disagrees with your premise as well.
Yeah, it should probably be phrased as "You don't actively contribute to the growth of the problem".
Consider for a moment that your argument actually contradicts your other argument. That is to say that when you state that victims speaking up helps combat the problem while them keeping quiet contributes to the possibility of more victims... what you are saying is that them (the victims) hiding/denying the existence of the problem and allowing others to deny/hide the existence of a problem makes the problem worse, by allowing more people to be victimized... But then you're saying that no, actually denying the existence of a problem keeps it from getting worse... Don't you see that you're contradicting yourself?
No, I don't think I'm contradicting myself here. The difference is still the case that a person can bring to the table. A victim can bring an actual case, with evidence, against a specific person. That's guaranteed to have some effect other than maybe in the most severe cases of power imbalance. A person who just preaches how bad everything is and how we all need to change stuff is in effect just a fearmonger until the moment actual victims come forward and break the silence.
So here is my take on asking victims to be martyrs, defining their role in combating the problem, and what our expectations of them should be... I'd compare it to soldiers that have been grievously wounded in combat. What expectation/responsibility are you going to reasonably place on them for solving the problem of unjust wars, imperialism etc? Sure you could say that they are in the best position to speak out, make a difference etc... but I mean, a guy already lost his leg... hasn't he suffered enough? Hasn't he given enough? The rape victim has already suffered. Asking them for more isn't reasonable or, as you say "fair". And that's the point, its not fair, so no they don't have any responsibility and we don't have any moral leg to stand on claiming that they do. If they want to speak out, then fine but trying to attribute any blame or responsibility to them just isn't fair.
Yeah, but life doesn't operate on fairness. That's the funny thing about you guys, you think things are bad, you want change, but then you argue that it is more important that victims get "fairness" than it is that we prevent future victims from becoming victims by blocking the ideas that would create change. You want results, but you don't actually want to foster the cultural narrative that gets results, instead you argue for the exact opposite and believe in this magical fantasy world where rape and sexual assault just vanish if we all just want it enough.
It is simply a fact that, if you want actual change, then some people will likely have to bite the bullet and go the extra step. That is, as I stated before, not something we should request from individuals, it is not something that we should condemn victims for if they don't have the strength or will to do it, it's not something that is "fair", but it is totally something that as a society we should encourage if we want change, and it is a statement that we should be aware of - victims who stay silent, that's exactly what a rapist wants.
Because let's be honest here. What's currently happening, with people speaking up, everybody being morally outraged and people telling the world about the terrible things they've done don't mean anything in the long run. The current hysteria will die down sooner or later, and then it's either back to square one - which is exactly where you're leading us - or it's into a future where victims speak out and thus prevent the cycle from continuing. Because the rapists certainly won't, and the public only can because people speak out about what happened to them.
