I can't help myself here. The "caveman" as you call him is clearly a pre-christian era norseman! That hair, and the clothing are clear tongue in cheek indicators(don't believe me, go check out Hägar and read a few of them). Further I think you should note that by your own presumptions of the superiority of Caucasians there would be more Caucasians in the tech field then other breeds of human, so if the article is about the backword(pun intended) movement of Geeks and intellectualism, then clearly the image meant to illustrate this should be a "regressed" Caucasian. I would suggest that before you go storming around on what is clearly a pet issue for you, you actually check the context of the article and the consider that perhaps someone purposely chose something for it's applicability and not for a biased attempt at political correctness.

by my society I was referring to gay society, not society in general.
