I agree. Just look at world history and you will see that European and Asian cultures were nearly wiped out by their poor hygiene behavior which caused fatal diseases like the plague, yellow fever, smallpox, measles etc. This is why gemaine warfare is banned because it was the germs from Europeans that wiped out 200 thousand tribes of Native Americans. And they lie about coming to Jamestown in 1619 and was welcomed by the Native Americans. Prior to their arrival, many of the Native Americans who lived there had died of smallpox. That's why it wasn't conflict between the pilgrims and Native American because the Native Americans who were left were either sick or dying. So it was easy for the pilgrims to enter the land unharmed.
And with Africans.....at first it wasn't so much disease that destroyed Africans in Africa cuz if so the African slaves would have died the moment they set foot on the new world. What was destroying Africa...was separation from culture, castration and FGM. The Arab Slave traders were castrating the men and converting them into Islam and turning them into eunuchs either to guard the harems or fight in their military. With the African women and young girls, Arab slavers performed FGM and conforming them into maiden slaves to care for the harems and the children inside the harems...since the only thing the harlots [from the Balkans and Caucus Mountains] knew to do was lay on their backs for the sultan. And the sultan used the African maidens to raise their children for either military[sons] or harems[daughters].
On the other side....African Diaspora…..you don't have castration or FGM per se cuz massa needed the slaves to work in the fields in the new world and the Americas. Can't do that if you're hurting down there or dying from the loss of blood. So in both instances Africans were concern about their gentiilia[sp] cuz fast forward....during Jim Crow black men were hunted and castrated for massa's "game" pleasure. Plus the African slave was decidedly preferred in America because massa couldn't keep Native Americans alive [from the disease he brought] long enough to consider them for slavery after the invasion/wars. Mainly because Native American's immune system weren't as strong as Africans- who didn't succumb to all those nasty deadly pathogens circling the new world. As Native Americans dropped like flies.....African slaves were still working the fields and in massa's household. So it was after slavery......massa decided to use the method of castration on black men all the way to the 1960s. Today murder, incarceration, poverty, miseducation, open racism all have replaced castration. As far as disease? When you take away the knowledge of the culture? You set the culture up for demise. Cuz Africans had the cure for every disease known to man when they knew who they were as a people. Now? Many of us don't know who we are and is why massa can kill us at the drop of the hat with his diseases and all the above. But!
