After the terrorist attack in Paris we all have must seen that a lot of people is taking the initiative to support the people of Paris, pray for them and show empathy for them by changing their profile pictures (DP is the word you mostly use) across the social media platform and also a lot of dedicated HASHTAGS for the same and in some more uncountable ways. People were dead against the scenario and did burst into anger (even somebody did not have any idea about the whole scenario also, but they "supported").
Don't get misguided by my words so far. I am not saying that I support ISIS or any of the similar kind of activities which harms and endangers the human race and peace in the world creating violence in the name of rebellion movement. The terrorism can't be eliminated neither by weapons & revenges nor with a vengeance. The mentality of the people and the across the world is expected to be changed so that there are no need of weapons to deal with, as there will be no need of those heavy metals.
