Nationalism a curse or progress

Good Evening Everyone! This is the Final round and so far my opponent has failed to give us any insight or knowledge as to How nationalism has been a progress for humanity. He is still stuck on the dictionary meaning of nationalism while i have provided everyone PUBLISHED ARTICLES FOR EVERYONE TO READ AND COME UP TO THEIR OWN CONCLUSIONS ( without me influencing their opinions on them), yet he refutes those PUBLISHED articles and came up with his dictionary meaning of the word nationalism and states, " loyalty and devotion to a nation; especially : a sense of national consciousness exalting one nation above all others and placing primary emphasis on promotion of its culture and interests as opposed to those of other nations or supranational groups" without stating any references or citations himself, but for sake of my opponent, ill stick to his definition in this concluding round and give my closing argument by explaining through his interpretation of nationalism of how evil this curse of nationalism is for humanity. And for his sake i plead him to rather than giving rebuttals and counter arguments to the statements i have made, PLEASE ENLIGHTEN US AS TO HOW NATIONALISM IS A PROGRESS FOR HUMANS because so far you have not given us any points and have failed to build your case. PLEASE EXPLAIN TO US AS YOU ARE PRO- TOWARDS NATIONALISM, HOW IS IT A PROGRESS FOR HUMANS, PLEASE BUILD YOUR CASE!!! LET THE JUDGES OF THIS DEBATE DECIDE WHO IS RIGHT OR WRONG!! Moving on, in all of my previous arguments on this debate i gave various reasons why nationalism is a cancer for HUMANS, i linked various problems, difficulties, trials, tribulations and ills to nationalism, for all of these problems are directly related to nationalism. Keeping in mind the DICTIONARY meaning my opponent has provided, i link racism to it, for two HUMANS ( and please mark my emphasis on humans) born in two separate nations with different cultures and interests, placing primary emphasis on promotion of their cultures and interest will never see each other as equals, one will always try to place the other as inferior to him. White hating black, yellow hating brown etc. I link Division of Mankind to nationalism, humans against humans in forms of nations, killing each other on the orders of their respect governments or authorities or leaders just because things were not going forward in line with their INTERESTS. Hence i also linked GENOCIDE and Ethnic Cleansing for there are many examples in our written history to prove how nations committed these crimes in the name of nationalism, Baluchistan one the recent examples a province of Pakistan trying to seek independence from it, Germany the biggest example of what it did in WW2 and WW1, Kashmir another example trying to seek independence from India, Palestine is another example, Serbia the worst of them all, i could go on and on, all in the name of nationalism. This evil of nationalism has brought nothing but distress, death and destruction to Humans. It has divided mankind, a single species into different unnatural groups, each competing the other for material gains and interests and they go to the extent to eliminate the other group if deem necessary to them. In the end i would like to say a few words to my fellows humans...... Ye have divided again, oh mankind. Don't ye see how your Lord diversified thee, diversifying mankind giving ye different colors, shapes and sizes, intelligence, qualities, strengths and weaknesses so that ye can distinguish between one another and made it easy for thee to recognize each other. Thy Lord diversified mankind so that ye may unite and strengthen through diversification and build a heaven on this earth through your own deeds. But look at what ye have done mankind, ye planted a seed of division in mankind which has grown into an evil tree bearing out fruits of oppression, racism , inequality, exploitation and persecution in mankind. It is your own deeds which has turned this garden into hell. Plant the seed of unity in mankind walking in the path of your Sustainer. Care for it like a gardener with the tools of love, respect and trust. And ye will see a beautiful tree of unity sprout in mankind giving righteous fruits for all. Care for all in mankind regardless of their color, beliefs or race. Don't ye see ye are one kind, the same species. Love rather than hate, share rather than hoard and Unite rather than divide, for ye can make this earth a wonderful adventure and a replica of the heavens above by your own deeds. Thank you and may God bless all!!! (I believe in the God of Abraham and i follow the laws given to Moses, Jesus and Muhammad)
