The goals of purposeful ignorance are toxic. The intentions are to harm others, in order to achieve a perceived personal benefit.
It's worth listing these goals. There are three main ones.
THE FIRST GOAL OF PURPOSEFUL IGNORANCE
To reinforce a reality, in which people with ignorant, toxic, and harmful ideas and intentions must perpetually be debated, which subtly insinuates that in matters of public policy they are the people whose permission must be sought
To people complaining “you’ll never convince me with that attitude” when they get mocked for saying purposefully ignorant shit: We’re not trying to convince you. We’re trying to mock you, for being ignorant, to convince everyone else that purposeful ignorance deserves mockery.
If you come with racist or sexist or transphobic or anti-science nonsense, you don’t become some reclamation project who must now be convinced of anything. You’ve proven yourself unworthy of the effort. You become an object lesson on how to deal with toxicity and ignorance.
Assholes of the world: convincing you that bad things are bad and good things are good is far less necessary than you think. Now shut up while we talk about you.
The only thing I would change about those lines, which I wrote not expecting any readers at all, is that I wouldn't say "nobody cares about their motives" because obviously motives are of interest to historians.
Awareness of wrong carries a clear moral mandate to admit it or reject it. Admitting it carries a clear moral mandate to help fix it, or refuse to. Agreeing to fix it means paying the cost of repair.
I'd observe a lot of people don't want to know, because they don't want to pay.
This is why conservatives have set their sights against awareness itself.
My suggestions: Stop using "viewpoint diversity" to mean "conservatives get to talk more" and recognize that the conservative reaction against academia is mainly driven by a broad *expansion* of diversity in voices, which conservatives categorically oppose.
There's a reason that conservative framing around diversity boils things down to roughly two sides of "conservative" and "liberal."
It allows them to ignore the fact that we ALREADY have broad diversity, and to frame themselves as the marginalized "side."
And so: voices of every ethnicity become not a multitude of ethnic voices, but "ethnic studies." And so with every facet of gender studies, and religious studies, and all of THAT get boiled to one side: Liberal.
Against which conservatives posit themselves the whole other side.
