People are racist because of fear. Change my opinion.

Everyone in the world is afraid of migrants and immigrants not because of hatred with "we are better than you" or jealousy with " you come here and benefit from our policies and resources and do better than us" but because of fear of "they might someday outlive us and push us to extinction", just think from an open mind, every species on the planet has this fear and ostracises kin slightly different from them, this is deeply embedded natural fear , that no matter how ever rational a mind is cannot overcome, you need to remove the parts of your mind that make you human to kill this.

So better to prosper in your little bubble or country and live in peace.
