It is dismissed as rightist, whatever that means. The Left won. And since then the young in India have felt that to be considered intellectual, one must belong to the Left. Time was when the so-called Left included a rainbow of parties like the Socialist Party, the Praja Socialist Party, the Communist Party of India and many intermediary parties of mixed socialist content like the Kisan Mazdoor Praja Party. The socialist content of political parties died with Indira Gandhi.
Socialism is a dead ideology.
Even in the CPM there is precious little socialism. In fact, none. And there is even less Marxism. The Leftists run two states, West Bengal and Kerala through muscle power. No matter how vile the RSS is or is not, it has not resorted to killing on the scale that the Left frequently indulges in.
