(1) A citizen who thinks independent of party politics :
Why ?
Because a citizen is not a member of a political party. And so not bound and blinded by any particular ideology. It is not necessary for him to follow party line.
The main aim and objective of political parties is to gain seat of power. To achieve this aim, political parties may resort to any tactics that may be harmful to our national interests.
The aim and objective of citizens is to choose a right dispensation for governance which can run affairs of nation and state for the common good of the people in general.
This can be possible only if citizens think independently, scientifically and rationally. Even one of the fundamental duties enlisted in article 51-A(g) of our constitution enjoins upon us, the citizens, to develop a scientific temper, humanism and spirit of inquiry and reform.
(2) A citizen who explicitly expresses his displeasure to the harmful acts of politicians such as personal derogatory remarks for each other.
&
(3) A citizen who encourages genuine appreciation of a rival by a rival where it is required. Scientific temper and the spirit of inquiry are the instruments in the hands of citizens to judge such things.
Why ?
Because these two things will promote magnanimity and help reduce enmity and hatred. Members belonging to different political parties are all Indians and in that sense, brothers and sisters. Where is the need to spew venom? They do it because we, the citizens, clap thunderously, when they, the politicians say venomous one liners to arouse our base feelings
(4) A citizen who explicitly expresses his displeasure to the vices communalism, castism and parochialism etc.
Why ?
The era in which world is flat and has been reduced to a global village, these three vices will take us back to the dark age in human history.
But the core question is, just the expression of displeasure by the citizens can bring the politician back to the right track ?
Emphatic YES my citizen friends, because all politicians are highly sensitive to the fragrance of VOTE. And that fragrance of vote emanates from our body language.
