The reason it hurts so much to separate is because our souls are connected.
We are not sheep or cows. God didn’t create fences for us or boundaries to contain our nationalities. Man did. God didn’t draw up religious barriers to separate us from each other. Man did. And on top of that, no father would like to see his children fighting or killing each other. The Creator favors the man who spreads loves over the man who spreads hate. A religious title does not make anyone more superior over another. If a kind man stands by his conscience and exhibits truth in his words and actions, he will stand by God regardless of his faith. If mankind wants to evolve, we must learn from our past mistakes. If not, our technology will evolve without us.
