While I agree with every word you wrote, I don't know how you can maintain hope in this. Just weeks ago, there was an HN thread, where between the article and comments there were dozens of stories of women suffering harassment. And yet still, multiple people here commented to the effect, "No real women in my life tell me about this stuff, the rest must be hysterical." I'm paraphrasing, but it's not an unfair characterization.
I see it in the same light as folks that have a completely 100% incorrect understanding of "[institutional] privilege" and are already at a weird level of anger by time they enter any conversation about it. They seem to be unable or unwilling to entertain, let alone accept, evidence contrary to their closely held beliefs (and there's evidence to back it up).
Meanwhile, the groups that get frustrated at continual, constant marginalization from those with their heads in the clouds, or try to advocate for causes and less ignorance, are given three-letter acronym labels which are used to deride and derail.
And within 5 minutes this reply is swinging +/-4 votes with no replies. How absolutely utterly depressing.
