President Pervez Musharraf's son Bilal and rock band Junoon's guitarist Salman Ahmed, who till recently were good pals, are now clashing in cyberspace over the imposition of emergency in Pakistan.
Ahmed, who was a supporter of President Musharraf's policies, especially his stand against terrorism and his vision of "enlightened moderation", has been prolific on the cyberspace, calling the President a "dictator" and "Pharaoh", since the imposition of Aemergency on November 3.
This provoked an angry response from Mr Bilal Musharraf. In his letters, which have now been taken off most websites, Mr Bilal Musharraf has accused Ahmed, who he says was a close friend and a spiritual guide of sorts since 1998, of indulging in "venomous rhetoric" against his father.
"No one is perfect, I realise. However, to the extent one can, one must try to reduce one's integrity gap which someone defined aptly as the difference between lived values and stated values," he said.
In his response, New York-based Ahmed wrote that despite their close friendship, "staying silent under the present conditions that Pakistan is undergoing, is no longer an option".
"My prior public support to your father's government along with that of the vast majority of Pakistanis was given in the belief that he would deliver on his public promises to fight extremism, respect civil institutions, bring accountability to corrupt politicians, open up a free and independent media and reduce the immoral gap between Pakistan's rich and poor," Ahmed said.
"My support for your father's government was never meant to be taken as a blank cheque for the state machinery to run amok and start dismantling civil institutions, making deals with crooks and plunderers, treating civil servants like common criminals, kidnapping and killing innocent Pakistanis under the guise of the ‘war on terror'."
Mr Bilal Musharraf also said Ahmed's association with Mr Musharraf was part of a "marketing strategy" by the rock musician.
