In the 60s and 70s that changed: Black Guys kicked the asses of White Guys; so did Asian Guys; so did All-over-the-World Guys.
Then ... it was the turn of Women to kick the asses of White Guys (remember Mr. and Mrs. Smith?). And, recently, how about Salt? And countless other films.
And in the past couple of years, Little Girls are kicking the asses of White Guys. See Kick-Ass? And Hanna last year?
What's next? Parakeets? Gerbils? Asparagus?'
Pity the poor White Guy, his ass kicked by every form of life.
