Rajeev's credentials? He is an RSS activist who contributes narrow extremist view-points of RSS on the net.
He has a fan following of people who share his Islam-phobia and fundamentalist view points. When he write anything else, he is completely out of depth and ignorant of the topic as in the present case.
If you Google him you will find his oeuvre, a typical one is that in which he theorizes that the tsunami that killed 25000 opeople world-wide was sent by Gods as a punishment for the arrest of Kanchi Sankarachaya by the TN Government. Also, his articles (in rediff itself!) after the Gujarat riots are revealing of his journalistic inclinations..
He is a contributor of articles in similar vein to Rediff.
