First of all why is this enough for you to call Shezaad a queen? You're underlying anger and hatred is strange.
What do you mean Balaji is allowed to have a go? And Shezaad is not? This is not true. No where in ICC rules does it make for an allowance for a player(a fat digusting one), to have a go at another. Its something that is merely allowed.
Shehzaad having a go at Balaji is not a big deal, and is something that happens all the time. Players other than the bowler get involved with sledging very, very frequenly.
In the NZ test, Jesse Ryder constantly berated Pakistani batsmen, yet this was allowed. But when Pakistan returns the favor, people cannot help going nuts and providing meaningless arguments.
Shezaad did nothing dozens of other players do every year, without getting screamed at. FACT.
