Waiting for your turn to speak isn't the same as being silenced. Being asked to listen to the opinions of others isn't the same as being asked not to have an opinion. 'Entitlement' is the relevant buzzword here.
Even a quick skim shows several references to shutting up as well as how it's not an ally's place to discuss racism. I frequently see similar idea whenever a discussion of what being an ally is, comes up. I'd say that being an ally is being asked/told to be silent
Note: I was just saying on another forum that the liberals would often reject that whites in minority-dominated areas deserved any help for structural racism they face but then demand with straight face that same whites needed to fight racism minorities face every day. The feedback indicated people didn't buy that or care to respond. See last paragraphs of No 4 on this list.
In mostly black schools, whites aren't given a turn to speak on this. They shout over us in unison with some beating the shit out of the white people that disagreed with them. That was common for years in all of the ones my brothers and I went to. On public media, they just tell us we don't understand, can't understand, are the oppressors, etc and we need to stfu on permanent basis. Also, we need to promote their message, support their pro-minority programs, and step aside in their ensuing rise.
This isn't about turns. It's about them dominating people they disagree with much like others dominated them. Group vs group politics. They neither care what we have to say nor want us to be able to get our message across. Personally, I listen to and try to help them but not vice versa. They're clear we don't count.
Note: There's certainly exceptions to the above rule as always. I'm not talking about them.
