BW dominate the media landscape when it comes to IR relationship content—just glance at the biggest IG pages in the genre (outside of OP's suggested YT sphere), and the bulk of them largely trace back to BW.
It’s almost awkward by comparison, as women from other racial groups (e.g., white women) don’t seem to engage in such extensive campaigns. Instead, the men often take the lead in promoting these dynamics in the media (e.g., WM/AW content or the 'Passport Bro' movement).
That’s why every viral Tweet about them nowadays is either them complaining about BM dating IR, or them getting exposed for their hypocritical stances towards those relationships.
