Is it possible that white Americans and black Americans may be genetically inferior compared to their European and African counterparts respectively? They seem to have a proclivity for exceptionally bad habits (drugs, crime) and in much poor health (notice all the obesity, which you don’t see in Europe and Africa).
What you are seeing is the effects of a despotic establishment warring against its own citizens, not some supposed genetic deficiency. You should hang your head in shame.
It has a lot to do with food quality and daily living.
Italian food, for example, is more pure and natural...the way God made it.
America consumes Frankenfood, with pesticides built in, GMOs, high fructose corn syrup instead of natural sugar, etc. Americans also have a ton of chemicals in their soaps, shampoos, hair care and facial products (including adrenal blockers that mess with the endocrine system).
Plus, Europeans tend to do a lot more walking in their daily lives, versus Americans who sit in an office, sit in their cars, and sit on their couches.
