He said this while speaking at the "Jan Raksha Yatra" march of the BJP, taken out in protest against attacks on its workers in the southern state, ruled by the CPI(M)-led Left Democratic Front (LDF).
"These communist groups with a misguided political ideology are selectively killing those who have a nationalist ideology and who are working for the betterment of the country," Choubey said and added that the BJP-RSS workers would "put an end to the communist violence" in Kerala.
The "Jan Raksha Yatra" against political violence in the southern state was launched by BJP chief Amit Shah in Kannur in Kerala on October 3.
From the next day, the Delhi unit of the saffron party has been holding daily protests at the CPI(M) office here. Union ministers have taken part in the protests on all the days. The fortnight-long demonstration is scheduled to come to an end on October 16.

"This violent leftist ideology will disappear in the wave of nationalism and communist politics will come to an end in Kerala," he added.
Kerala has been witnessing a cycle of violence involving the workers of the CPI(M) and BJP-RSS, with killings and attacks reported from both sides.
The incidents of political violence have gone up since the LDF came to power in the southern state in May, 2016 with both sides blaming each other for the developments.
