I think the reason why whenever a Black celebrity is caught up in these scandals, they stand out more than the white ones is obviously, as some of you pointed out, racial propaganda and stereotypes at play.
I also think it's due to Black celebrities being more prominent and renowned. A lot of those White names outside of well-known figures like Trump, Giuliani, Weinstein, and Epstein, others such as Gaetz, Alex Jones, etc don't have the same status (clout, notoriety, etc) as the Black entertainers (Cosby, R-Kelly, Puff Daddy, etc).
Now, you could say that's part of the news not reporting enough on white scandals in favor of racial stereotyping and promoting propaganda against Black celebrities, but we also overestimate how well-known someone like Gaetz or Alex Jones is to the average citizen walking down the street.
They may have big fan bases for their type of work but they're nobodies compared to Puffy, Bill Cosby, or R-Kelly (among others) so when they get caught up in shyt it might not resonate or gain enough attention to the average eye.
