The difference is... one of these colors is the only one that has centuries of privilege and power, a lot of times used violently, and the only one claiming victimisation when someone mentions "how about equality/equity, or even just acknowledging the privilege you have?".

It seems to be a thing of decorum not to explicitly say "I will only date $color people". Saying those words out loud or joining this site exposes you as someone with an inferiority complex whose only answer is arrogance about a shared identity.

And let's be real, members of those sites are probably not just "expressing their dating preferences", but probably have that inferiority complex that racists have. Does this theory apply to the other colors? Perhaps...
