I personally think that all these attachments to skin colour are bullshit. Regardless if someone gets attached to being white or black. It is an illusion and obsolete mental attitude that has no future if humanity wants to intelligently and sustainably progress.
Where we are born and what physical traits we have is just a lottery. It does not define who we are and who we should be. We choose do identify with something so why identifying with things that only perpetuate divisions between us.
