I think it's just Republicans throwing what have traditionally been Liberal Democratic stables back in their faces where, as long as it sticks in the mind of the least critical thinking voter, it works. Is #MeToo a liberal thing? Call out a Liberal when it seems they're in violation of it. Going after the current Supreme Court justice for what he did in his past as it relates to women? Throw it in a Democrat's face when it's useful (and to the uncritical viewpoint which ignores what his ex-wife says, relevant.) Dems calling out Republicans on intolerance? They can make that shoe fit any day of the week now, when the ideas out there are so toxic that Liberal Democrats try to eject them from the discussion. Nevermind if someone calls an entire nation of people filthy raping criminals, what matters is that you don't think that should be part of the conversation, you racist you.
It toes the line between calling out hypocrisy (how people on the Right see it), and weaponizing movements for their own uses (how the Left sees it.) Or to put a fine point on it, if these things were important to the Right they would have brought them up by now prior to using them as weapons against their opponents. It sucks but it increasingly looks like it's effective. The substance of these claims get ignored when it's just this stupid "Us vs. Them" narrative that pretty much everyone has bought in to, whether they want to or not. It's an attempt to suck people in the middle in to either side of the struggle, by increasing their confusion as to what's legit and what's not until they cave and take a stand with one side or the other because they feel morally obligated to. If they go Right, great. If they go Left, it's just another "libtard" to hurl accusations at. And the same thing works on the other side. You're expected to take a strong stance on issues like #MeToo, Intolerance, etc.. on the Left. I remember that was the tone of the forum right around the election. I remember several left posters here saying "No half measures anymore, no compromises. No more trying to bring people to the table to talk, that hasn't worked. This is war. If you're not with us, you're part of the problem." That too is an effort to shove people on to either extreme of the spectrum. It's not enough just to say you don't support men abusing their power and privilege to get sex out of women, and getting away with it. You must be outraged as well. Anything less than that and your moderate viewpoint gets drowned out, or you get accused of essentially being a collaborator, regardless of whether you identify left or right.
Or just TLDR: this is what political radicalization looks like on a large scale.
