All have a responsibility to talk sense at all times. And, leaders have to have more sense than ordinary people when they talk, because they are respected for whatever reason. Amar Singh, Raj Thackeray, Abu Azmi, Udhav Thackeray, and all our politicians have to assume responsiblity for the mess we are in. Atleast once, Mr. Advani said it right that the Indian politicians do not behave properly. I am sure he indicted his own partymen, including himself, as well.
Gone are the days when these words carried a lot of meaning.
Today's politician is struggling hard to get power.
Anyhow.
In the process, he becomes irresponsible, irrelevant, and often even vulgar.
He get carried away by the few who clap at his every alphabet little knowing the relevance or repercussions.
The more inexperienced the guy or the doll, the more irresponsible he/she would be.
As you have rightly said, even a senior and well experienced man like Advani blabbered in the land of naapaaak that made all at home so jittery.
This man they call raj in maharashtra has very little experience and very giant ambitions for which he seems to be refusing to groom in the conventional manner.
Those who grow unconventionally and unconstitutionally ultimately become Hitlers.
