Your points are correct but I disagree with your conclusion. It's not deciding that some people will be sacrificed (also a bit extreme of a word choice for feeling put out by discussions of a demographic you belong to), it changing the proportion of people sacrificed in the hopes of reducing the number of people raped. The shift is away from teaching women that it's all on them. Their fault or their responsibility. Objecting when the balance changes says that it's not sacrifice you object to, but it being men. "The status quo is better than the cost of fixing it".

When you ask why men should support anti rape education if it makes them feel bad, the answer is supposed to be "because they understand rape is worse than the cognitive discomfort of discussing awful things people like them did".
