If they had accepted, their perceptions would have been different.
If one person says: “I am white/black people”, that person tries to bring own race into the forefront firstly.
If one person says: “I am a woman/man”, that person tries to bring own gender into the forefront firstly.
If one person says:”I am a christian/muslim/jew,” that person tries to bring own religion into the forefront firstly.
This list goes on. I’ve rarely seen the people, who never told about those particulars. They are the minority on this planet. If most of the people had accepted being human at the beginning, and they had started to conversation “I am a human”, in that case The differences between them would have been minimized.
But we all know, they will never accept. Because they love to fight so much more than everything, as I said before:)
That’s why, they are a hopeless kind into the universe.
