Here is my theory, and I think it's a beautiful WORLD! A BLACKED NEW WORLD ORDER:
White bois enjoy interracial sex and/or cuckold fantasies.
It really is a kink based on a damaged ego, a bad self opinion and a masochistic nature born from a lot of pain and abuse (usually endured during childhood and teenage years). If these psychological problems could be resolved, THEY NEVER ARE....we train our brain to like it for so many years that the neurological pathways are almost impossible to dissolve. "Once you go black, you never go back" is not a lie.
Why so many white males are into this kink? The short answer is : because of a culture that encourages them to hate who they are. At some point during the development of your psyche, your brain managed to turn the pain and the self-hatred into pleasure... and became masochistic. It's just a good ol' survival mechanism, because it was either that or suicide if you didn't have a positive role model around you (you probably did't have one, like millions of young men).
Though I can not fault your ideas, and beliefs, that it does make sense, I must point out how negative you make it. I think it's only natural to self sooth and cope with your issues in a safe and accepted manner. Part of this you didn't mention is the point of view failed white males have, the pressure to be part of this "white privileged" culture and to accept that so many before us made it so much more difficult to succeed as a white male. It's not a fault to be who you are, It's not a wrong direction, it is accepting what abilities you have, and what you lack. Finding positive goals, and learning about a place where you can be useful. this can be beautiful and life enriching. I hope to help others find their bliss.
Not sure I agree why isn’t it just recognised superiority
Yes, I definitely deserve to be a sissy cuckold!
