The community is called "Fediverse", and this is about the fediverse, so yes it is the correct audience.
And there's plenty of anti-Blackness on Lemmy. In fact there's even a bunch of anti-Blackness in this thread -- as somebody on another instance said, it's illustrates why other instances have defederated lemmy.world! So, if you're looking for examples, have a look at this thread.

Could you help me find the comments you are referring to? I can't seem to find them, and I'm worried it might be because I'm subconsciously anti-Blackness
If you can't find them, then (like many people) that's a sign you're used to an environment where anti-Blackness is normalized. So, imagine a Black person reading this thread who's been targeted by racism on the fediverse. What comments would they think are dismissive of Black people?
