As it led to a stir on Monday, it was also reported that his 'effigy was burnt' by the protesters including members of Kerala's United Nurses Association (UNA).
The UNA state president Jasmin Shah sought an apology from him and said that their forum would send a legal notice to him.
"We will sue Kumar Vishwas under IPC 499 and 509", she further said.
Kumar Vishwas remarks on Kerala nurses
Vishwas made the objectionable remarks in 2008 during a stage show at the National Institute of Foundry and Forge Technology in Ranchi.
In a 23-minute YouTube video, he is heard as saying, "Pehle jab aadmi bimar padhta tha bechara purush to jata tha haspatal mein toh tassali rakhta tha. Pehle narsein jo thee Keral se aati thi, kaali peeli si. Toh moonh se 'sister' nikalta tha. Andar se aavaz nikalti thi ki 'Allah, sister hi ho!' Bahut saari ladkiyan profile pe photo lagati hi nahi, ki pata nahin kya ho jaye. Ab aaj kal to nurse bhi north India ki aane lagi, ekdum bilkul shandar."
Some Youth Congress activists vandalized newly inaugurated state committee AAP office at MG Road in Kochi, who claimed that AAP leader's remarks were laced with "sexist undertone".
Police said Youth Congress workers took out a march to the AAP office on MG road in Kochi and threw stones and ransacked the office. They reportedly threw eggs, broke some chairs and windowpanes.
They also shouted slogans against AAP and Vishwas, sources said.
The 45-year-old poet-turned-politician has earlier also been booked for hurting Muslim sentiments with objectionable comments on the procession of Muharram during a Kavi Sammelan.
Mallika Sarabhai, who recently joined AAP has also accused Vishwas of making misogynist and anti-minority comments.
AAP leader plays it down
"He was a bard and in a lot of these videos he is trying to raise a laugh. If it is objectionable he should be censured. Remember that this is a party of men and women from diverse backgrounds and upbringing, not all of whom are sensitized to gender or other issues. They need to be asked to watch carefully for comments that can be abrasive," Kamal Mitra Chenoy, former CPI member who just joined AAP, said.
