THE canker seems to be in the air. The level of social discourse in the city is plummeting. Especially in media circles. Elegant parties which once resounded with the bussing of cheeks and a happy exchange of news and gossip, are now routinely witnessing the ugly wreckage of ideological and commercial ambush. At a recent party in a five-star hotel in Delhi a platoon of senior journalists spent time stalking ostensibly anti-BJP mediamen with personal barbs. With the delusionary swagger of those close to power, they were also heard warning their rivals of dire consequences.
