Well - he has just announced it is a ruse, a guise - whatever - so that's not so much 'pretending' as it is pretending

And how do we know what colour the guy posting in these various 'dude' incarnations is anyway - Is there a post under any of the IDs that says "I'm white - here's the proof" - Has he ever had a gallery? I never saw one.
What if he is an angry black man? Or a slightly peeved person of mixed race? Or an irritiable 2nd generation Armenian? How would we tell?
I have seen several instances where a member has been assumed to be of one race/ethnic group by one (or more) other member(s) and it is always the fool making the assumption who comes out showing their own ass. If people have latent racism then I welcome anything that exposes that trait for all of us to see - regardless of what direction the prejudice takes.
