The party further said that Raut's opinion, as expressed in an editorial in Sena mouthpiece 'Saamana', would only aggravate the problem and lead to communal polarisation at a time when remarks by Sangh Parivar leaders are already spreading venom in the minds of people.
"The CPI National Secretariat vehemently condemns the statement by the Sena leader. Such a statement is most unconstitutional and undemocratic," party general secretary S Sudhakar Reddy said in a statement.
"In such a situation, Sena's talking on the lines of religion is most unwarranted, undemocratic and unconstitutional.
"Several statements by the Sangh Parivar are already spreading communal venom in the minds of the people of our country and such statements by Sena will further aggravate the situation and lead to communal polarisation," he added.
CPI also alleged that statements made by MIM chief Asaduddin Owaisi, who had thrown a challenge to Sena leaders to enter Hyderabad, too, would promote communal polarisation even as it described such challenges and counter challenges as "match fixing".
