There are a few problems with this line of thinking though:
1. What does temporary mean? What duration are we aiming for before white people can speak again?
2. Is collectivising people like this helpful? I've been spoken over by white people, women, other black people, all sexualities and gender configurations, you name it. I've no doubt also spoken over people in all these categories at some point in my life. At what point do we recognise that disagreement is a natural part of the problem solving process and not an attack? Don't get me wrong, I come across white people who simply don't want to listen too (interestingly enough, they're usually the wokest, Robin DiAngelo readingest of the bunch), but I also come across plenty who do want to engage and listen if they can have a conversation instead of a sermon.
3. I don't think you mean to suggest this at all, but I always bristle at the idea that black people are too weak to make their voices heard in the presence of white people. The idea that conversation needs to be "allowed" by white people is just no good as far as I'm concerned. Yes, these conversations can be difficult, believe me I know, but if we're not strong enough to have them unless the white folk "allow" us to speak, we have a serious problem. And if we do have that problem, I think it's one we need to look at ourselves for the answer to. We simply cannot embrace a mindset of needing to be permitted to speak about the issues we face.
4. You say that you cannot have a conversation with people who think their thoughts and feelings trump yours, I couldn't agree more with this. But if we're talking about silencing an entire group of people because of the colour of their skin, saying "we're already well aware of [their] thoughts and feelings", isn't that simply another example of believing that your thoughts and feelings trump somebody else's? Lived experience is all well and good, I don't mean to dismiss it, but it isn't the unalloyed truth.
I do expect white people to listen to me when I talk about racism, I expect them to recognise that I have a perspective they lack, but I also expect to listen and explain and try to understand why they think the way they do. To recognise that I don't have all the answers. That's how progress is made. Adult human beings simply will not, in general, sit quietly and silently accept ideas that they disagree with. This is basic human nature.
The idea that a conversation with a black person about race should be a monologue rather than a dialogue is only serving to make an increasing number of moderate white people check out entirely. I'm really not sure what the end game of this mindset is.
