Use of derogatory language

Sir,
I would like to highlight the matter of derogatory language being used by our national level leaders in India. Let me start with the fact that language is symbol of civilization. It reflects the level of maturity, knowledge, intelligence and sense of responsibility present in the speaker and or the writer. It also reflects the nature of personality and perception of the speaker/writer. So one should always try to use very soft and civilized language.
These days it is observed that a number of national level political leaders in the opposition using very unparliamentary language against our Prime Minister Narendra Modi which is very bad and shameful. It is our duty to respect our Prime Minister and should not show any kind of disrespect while addressing public rallies. We have a very good parliamentary system of government and we can speak about any issue in the house of parliament and can also make any minister or Prime Minister to resign, but we can’t abuse him publicly. By doing so we are insulting not only our Prime Minister but also the entire electorate of the country who have elected him. It is a universal truth that Narendra Modi is very honest and is trying his best to eradicate corruption from the country. But it is a matter of shame our leaders are blaming him baselesslly and that too with the remarks that their main objective is to remove Modi only.
However, I would like to advise them to present their own new ideas and plans for development instead of abusing Modi. I would also like to advise them to read Ramayana to understand the real and ideal personality of an ideal leader like Lord Rama who never lost his temper even when his beloved wife Sita had been kidnapped by Ravana the King of Sri Lanka. They should also note that even after killing Ravana,Lord Rama had gone to his feet to beg pardon and also to get some advice on politics. I hope that the learned readers and concerned leaders would consider my suggestions positively for benefit of all concerned.
