"Shinde seems to have lost his mental balance, otherwise he would not have been making such irresponsible statements," said BJP state president Jugal Kishore Sharma.
The party takes strong exception to Shinde's remarks on a nationalist party like BJP and a "thoroughly patriotic social organisation" like RSS, Sharma said, accusing the Congress of playing divisive tactics.
He said both Shinde and his party should concentrate more on issues like corruption and price rise which are concerned to common man, instead of making "unproven allegations" against BJP.
Shinde had yesterday stoked a controversy by accusing BJP and RSS of conducting terror training camps and promoting "Hindu terrorism", setting off an angry reaction from the saffron parties which demanded an apology from Sonia Gandhi.
