TX Ned you are right that"We have to do things for improvement of our Attack and Defense technology instead of wasting our time in such an emotional-commendable sharing s".
And an other thing is that this video is not the final or only representation of India so it will be a wast of time for thinking on it,because this girl is a representative of one religious political force"SHIV SENA" of India ,and that Sena wills that all Muslims should be killed.And that SENA gains power and unite people by motivating through this way on this idea that "All Muslims are our enemies,and they should be buried alive ,they have no right to live speciously in our country.
But it is not a new or unique thing on which we should discus ,it happens in politics that you need enemies on which you motivate people and unite them , and once they are united then use them for your own personal interests,it happens every where it happens in the name of religion sects nationality,language ,cast.
so for justice we should not take those things as the representation of state or nation of state,may be number of people of India have different vision then this.
But on the whole this will be waste of time to think on it, so it is the best way that keep progressing.
