'Street Side Fellow', Will such a PM teach us ethics? Mahua Moitra slams PM Modi on 'Didi o Didi' remark

At an election rally in West Bengal on Thursday, PM Narendra Modi taunted CM Mamata Banerjee and asked if she was going to fill the form from any other seat as well.
He taunted Mamata by doing 'Didi O Didi ...'. Soon after this, TMC MP Mahua Moitra got angry at the PM's post.
Mahua said that there are some people in Bengal, who are called' Rauker Chhele ', which means boys who sit on the road and call every woman ' Didi e Didi '.
She added, "The Prime Minister is also doing the same. PM, in a rally of lakhs of people, tightens up by saying 'Didi, O Didi' for an incumbent Chief Minister. Will he say the same to his mother?"
She asked, "Will he speak this for his sister? Speak for his abandoned wife? Will he say the same to anyone? How is this correct? Will such a Prime Minister come here and teach us ethics?"
