Dear Nationalists.

As Europe -and in fact the whole world- is increasingly gripped by successive waves of populism and nationalism, one can not be indifferent any longer.

I observe nationalistic people boast about their history, their country's economy, a very successful popular individual that comes from their country, their culture and lifestyle.

"Proud to be Irish, Greek, American, British" or whatever else is often used by people as a boastful expression for something they haven't achieved.

Or the recent "make America great again" and "taking back control," for Britain or any other euro-skeptic movement across the continent. " Greece for the Greeks, France for the French" and there is no space for anyone outside our tribe.

So all the above make me wonder; what are you so proud off? Your history may be part of your heritage and should be commemorated undoubtedly. But it wasn't you who achieved all these greatness, it was your ancestors, often numerous generations back.

Your national sports team winning, or one great athlete, actor, musician, artist or scientist excelling in international competitions or becoming successful, should not be making anyone "proud" apart from their nearest and dearest.

Except maybe your national sports team winning, which should give you some joy and satisfaction, there is little reason for such tribalism. Because that is exactly what it is; every nation uniting behind their "warriors" that beat and dominate over another tribe's. A bit primitive I think, the demonstration of such passionate emotion over a game.

Your country's economy is the result of successful financial policy decisions, that have been adopted often by previous generations. But not just that. Certain countries in favorable alliances. political blocks or geographic locations have positioned themselves as "elite" nations that have an advantage over other nations which less luck in their connections and "friendships".

So to be "proud" over often pure luck, is a bit daft. Finally, a nation's culture is often created by the constant mixing and influencing by other cultures from nearby nations, but also from countries far away since we live in a globalized world.

In an ever changing and hopefully uniting humanity, what should actually make a nation proud? Shouldn't be any development, policy or decision that positively influences and affects not only the citizens of this certain country, but also acts as a beacon that kick-starts a positive change for all human kind across the world?

Like when Ireland approved by popular vote to give same-sex couples, full and equal rights on marriage. That can stand as a beaming example, that could positively influence other nations to follow suit, extending equal rights for all LGBT individuals across the world.

Sweden is another case on its human rights activism and how it reacted on the refugee crisis that affects recently Europe. And not just this particular time.

Similarly, how many Greek islanders reacted to the scores of refugees being washed on their homeland's shores, the compassion and humanity they demonstrated, that is something that makes me proud as a Greek personally.

The above examples are just a few. Yet sadly, they do come fewer and fewer in our modern society. People need to be proud for something, to place themselves above others or other nations.

Well why can't these reasons be about the ways that your country stood as an example, pushing humanity ahead, modernizing and positively contributing in our collective global heritage currently, not just about its past achievements.

A bit of healthy competition acts as good motivation, but ultimately the goal should be focused on the greater good of the human kind.

If we keep looking back we can never move forward. If strive to look down on others, we can never be equal and develop together-or at all. If we only try to better ourselves, we leave many others behind. And this is not the way that humanity should be looking into the future, there is no benefit to live in an extremely unequal world.

We are making history as we speak. All of us, with our choices and policies we adopt, with how we treat other nations, minorities in our country and abroad. If we show our worse self towards everyone else outside our "tribe," what will future generations be "proud" of us after all?
