Stop asking Black people for evidence of the anti-Blackness. Believe them: it's real. If you want to see specific examples, do the work yourself to find them rather than asking Black people to do it for you.
IMO examples are exactly what should be provided on this page. The page would be much better if it were just 3-4 headings that looked like
Heading
Example quote 1
Improvement suggestion
Example quote 2
Improvement suggestion
Description and context
Also, why limit it to "blackness". What in the world is "blackness"? Sounds like black royalty "Your Blackness, how may I be of help today?".
Anyway, I'm not sure what prompted this, which is exactly why I ask for examples. I quit reddit (never was on twitter) during the exodus and honestly, the biggest change I'd like is for USAmericans to get their own instance where they can talk about their problems. Black US Americans deal with very different things than Africans and Europeans with African descent.
