Wrong Classification

Most often times, writing or talking about the world, I don't know how to use the plural personal pronouns. We, you, they... Who are these "we", "you", "they"?
          It depends on the "I".
          But who am I?
          For example, talking about the EU-Turkey deal, am I the Turkey as I am originally born in İstanbul and I am a Turkish citizen OR am I the EU as I am now an Italian citizen as well and I live in Italy?
          When I talk about the leaders, I should be talking as "we" since they are officially representing me. BUT they are acting in complete opposition to almost every core belief I hold. Under the conditions, how can I identify with them and say "we"?
          Okay, let me set apart the politicians, what about the population of Turkey and EU? There are so many among them that I cannot identify with at all. In fact, most of my beliefs and ways of seeing are in complete opposition to some of them too. So how can I talk as "we" for the community I live in?
          Coming to the refugees and migrants who are the subject of my attention... Even though I may say I have a nomadic soul, I have no common heritage or background with the refugees/migrants in question. I am not Middle Eastern, I do not speak Arabic. Even though I speak a bit of Spanish, I am not Mexican or South American. I am European looking, my religion is never an issue where I live, I am not poor, I am educated and skilled even though I am not in the workforce. I am not driven from my home, I live in peace and relative prosperity. In short, I have nothing in common with the refugees/migrants who draw the limelight of hate from certain groups. BUT I am defending them, i.e.  I am on their side.

So who am I supposed to call "we" as a group? I need to specify so that I can determine the "you" and "they". The only way to get out of this dilemma is to go to the highest level of identity: That we are all humans. As all other identities blur, what do borders serve?
