America is an imperfect nation. But that is true of all nations of the world. There are groups who suggest that Blacks due to American slavery history should seek residence in some other country. Some suggest for religious reasons Blacks should seek residence in some other country. Such suggestions are ill-conceived and lack proper consideration of history.
This phenomenon of leaving America is nothing new. It has been going on for years. For example, consider Liberia which was founded by the American Society for Colonizing the Free People of Color of the United States though some question their true objective (see Britannica Encyclopedia article). Also consider the people of Jones town of the Jim Jones event who left America for religious reasons. Liberia has not proven to be highly advantageous for the masses. Jonestown of course resulted in mass suicide and/or mass murder.
So beware of groups who preach and teach mass exodus from America.
America is still a great place for people of all races, nationalities, ethnicities and genders to live a great life. Yes, it is more difficult for some than for others but that is true in every nation. Moreover, God is able even in America to make things well for each of us.
