After the Civil War, or the Second American Revolution, as we call it down South, the Union was formed and our Constitution was amended to make secession illegal. By following this line of thought, it would be unconstitutional to form a separate nation in the US. It was already tried by the Confederacy in 1861, the results of which formed one strong nation under God.
At this time, the United States did in fact establish what Farrahkan, et al, are asking for now in the African country of Liberia, so named after Liberty. This was done by way of reparations, so the former slaves could begin a new life and have their own country. This territory was, unlike the barren land deal the Indians got, prime farming land with a decent climate...a good place to live. Government agents from the US made every effort to ensure a high quality of life for the newly established country of Liberia.
Former slaves who remained here, did so because they wanted to, thus becoming Americans. It was their decision to remain, and I believe they made the right decision to do so. It was a courageous decision for them because of the segregation which we all know about. OTOH, they probably stayed because they liked it here, and who can blame 'em? At least in the South, it's a shame the contributions these Americans made are not more emphasized, because they contributed much to our way of life as it is today. The resentment of the past is based on very complex issues of the Reconstruction period, some of which were perceived by conquered Southerners as punitive measures fomented by the Yankees; f.g. placing "liberated" Negro slaves as high city officials, in the case of Mobile. That action was imo a disservice to the slaves, as they did not have the education to carry out a job like that. It was insulting to ALL Southerners, black and white, and was probably the start of serious racism in the South. Even if race wasn't an issue in this case, the people would be howling mad about their city not being attended to "getting back on its feet" after a terrible war.
Well, thanks for bearing with me with how I feel we are all Americans living here in the US.
