just to add to the link in case anyone can’t click it:

Davis eventually went on to befriend over twenty members of the KKK,[16] and claims to have been directly responsible for between forty and sixty, and indirectly over two hundred people leaving the Klan.[19] Over the course of his activities, Davis found that Klansmen have many misconceptions about black people, stemming mostly from intense brainwashing in their youth. When they got to know him, Davis claims, it was more difficult to maintain their prejudices. He recounted his experiences in his 1998 book, Klan-destine Relationships: A Black Man’s Odyssey in the Ku Klux Klan.

Klan members have often invited Davis to meetings, and they have given him their robes and hoods.[16] In 2016, Davis estimated having collected 25 or 26 robes.

While watching this scene, I was thinking about if the choking was really necessary or if they could have gotten the emotional turmoil / betrayal across some other way. It didn’t fit that well with how they had interacted with each other up until that point

But later on in the episode, it looks like she again feels choked, but this time by the collar of her uniform. So if the intent was to set up that symbolism, I guess there is a reason for the scene in the post

I can’t say I’ve seen examples of this in reality.
