I think the only way you get there is by keeping dialog open with the people who do think it. If you refuse to listen to them, you strengthen their belief that they're seeing something other people are unwilling to look at.
And I think trying to "no platform" those people only strengthens their rhetorical position, making it easier for them to extract sympathy from moderates, which normalizes rape culture and quite possibly leads to more rapes. Which is really tragic.
But all of this is just a smaller part of a general failure of feminist policy to do anything with perpetrators besides punish them. Restorative justice is starting to catch on in feminist circles, at least in terms of lip service. But it's a tough sell, because it's completely at odds with the basic feminist methodology of "Step 1: Separate the situation into Oppressor and Oppressed. Step 2: Direct all available resources towards the Oppressed. Step 3: Fuck the oppressor up, if you can. Though you probably won't be able to. #lesigh #patriarchyamirite"
Of course, that is totally understandable. When you live in a society that systematically fails to punish perpetrators, and willfully ignores your calls to punish them, where else does that lead besides a laser-focus on self care and becoming psychotically obsessed with trying to punishing perpetrators?
And Men's Rights has a totally impoverished accounting of the situation, being able to say little more than "Not all men!" and "Women are perpetrators too!" which doesn't advance the dialog at all either. Those are orthogonal situations, and don't address the underlying issue which is that the victim/perpetrator dialectic obscures the root of violence, so it can never be pulled out.
We should all listen more carefully to the black civil rights community, who is leaps and bounds beyond the rest of us in drawing a nuanced picture of violence and ways to see through it to community healing.
