Is Dale Steyn a sook?

The recent media speculation surrounding the Michael Clark sledge to South African paceman Dale Steyn is not abating. We all know Steyn loves to sledge batsmen; he himself is a world class sledger initiating numerous exchanges.

Does that mean he, as a tail-end batsman, he is exempt from sledging? He feels that particular sledge was very personal and Clarke should apologise; video evidence may suggest that Clarke has already done so.

Recent ball tampering fines by South African bowlers Vernon Philander and Faf du Plessis in the past 12 months have tarnished the South African cricketing reputation to such an extent that the South African ethics committee publicly stated that "they are deeply concerned at the practice feeling that such behaviour cannot be tolerated from the national team."

Many media commentators are asking, what exactly did Michael Clarke say to Dale Steyn? Why did he take the comment so personally? Why has he taken to the media to vent his anger? Maybe, just maybe Clarke questioned why Steyn is able to gain early reverse swing in non-conducive conditions while other bowlers are unable to do so?
