I used to think of "Racism" and "Racist" as binary . You either ARE or are NOT a racist (and "I am definitely not!":). Life, and people smarter than myself, have thoroughly convinced me that it is a spectrum instead. The most open-minded, liberal, self-aware, "un-racist" people I've met realize there are impulses, tendencies, biases in all of us. Kind of like some of the smartest and most knowledgeable people are humble and aware of their gaps of knowledge. Thinking racism is binary and "I'm not it", blinds you to many aspects of it.
I remember a poor but enlightening joke a long time ago: "Those driving slower than myself are idiots; those driving faster are maniacs". I feel we may have similar personal line on racism spectrum: Those more close-minded than myself are "Racists!!!" those more open minded are "Woke!!!".
Which is to say - I don't think there's an easy, small, easily identifiable group that we should just lock up. We can start at the bottom of spectrum and quickly agree that "well these people are definitely racist", but pretty soon we'll get to the delta between our two lines, and then who gets to decide who is locked up / what should be censored? Whoever we eliminate, whoever we lock up, there's going to now be the next person/group/opinion that is now at the new bottom and needs locking up.
We clearly disagree on the second so can you elaborate? I believe formal legal censorship of an expression GIVES it oxygen and will subsequently increase it.
Brute force (and deplatforming is brute force) isn't an automatic recipe for victory in a war of ideas.
Sunlight is the best disinfectant. If you actually care about fighting racism, you have to be able to see it. You have to be able to understand it. You have to be able to track it. Driving racist rhetoric underground, making it hard to follow what groups are being targeted or what lies are being told, making it more difficult to identify who is involved in racist groups, what their numbers are, and who is listening to them doesn't help fight racism. Racism exists, and we need to face it. We can't just hide it away so that we can feel better or pretend the problem is solved.
You can't fight an enemy you aren't allowed to see.
Censoring it might keep the racists to their ugly selves, but that's OK with me.
