@BESW I informed Groody about your statement, Groody asks "For those of is lacking the long term relation with him, do you think he could post his findings to a meta?" — as far as I'm concered you did exactly that in your statment.
But if there is something that would help and not bother you much that springs to your mind, let me know.
The estra step is the essential thing, Groody wants a pointy link.
As far as I'm concerned, and I doubt there are many who would disagree, BESW's statement is good enough.
Now, the pointy link could also be a blog post of someone sourcing the racist rhetoric, dissecting it in less or more detail. It certainly doesn't need to involve a bunch of new writing from BESW, who would need to go back to the source years after the statement to do such a writeup.
The post that got AngryGM removed from the feeds was his post about COVID-19, in which he used racially charged epithets to refer to the virus. (And doubled down in comments, I might add.)
However, this specific post is not the whole picture. Subsequently, moderators and room owners came to learn that over the past couple of years Angry GM has engaged in patterns of behaviour that are at odds with the values we strive to uphold in RPG chat: kindness and compassion in particular. Giving his posts a place in our chat feed would be at odds with those values, so he no longer has one.
