Still doesn't validate your comment and remains anecdotal.  Maybe it seems to 'skew;  white because 'white' societies are the only ones that currently espouse full human rights and equality for all and therefore actually have laws against bigotry and racism. Thus, when counting racists, it is easy to do so in a society where they can easily be labelled as they stand against progressive laws and human rights. Whereas in many countries/cultures around the globe racism isn't even acknowledged as such and therefore isn't even counted/considered an issue.

Ask the Touaregs about the 'slaves'  that they still own having run in families for generations. Or hello the entire caste system. Or malaysia with its pro malay laws, the list of places with actual racism is huge, but alas in many parts of the world, this isn't even counted as racism or bigotry yet. This is where nominally 'white' democracies are ahead of the curve. At least we acknowledge racism and bigotry for what it is!
