If I am correct on this, OOA states that we all have a common African ancestor that evolved into homo sapien sapien before emigrating from Africa. While Multiregional states that we all have a common, African, ancestor that left Africa and then later evolved into homo sapien sapien. Both theories essentially state the same thing (that we all have a common African ancestors, and that we all evolved into homo sapien sapiens) so why do some people try to use Multiregional as a justification for the idea that the "races" are genetically different when there has been a significant amount of research that supports otherwise.

As far as I know the only difference is in non-Sub Saharan Africans who have a certain percentage of Neanderthal DNA. However, this does not negate the fact that we are all homo sapien sapiens (modern humans) regardless. I know all people don't use multiregional for ulterior motives but some people do. However, they never use OOA for those same purposes.

Why such a fuss?

As far as I know the only difference is in Europeans who have 1-4% lower-functioning human (Neanderthal) DNA. However, this does not negate the fact that we are all homo sapien sapiens (modern humans) regardless.

Why such a fuss?

(1) Exact Neanderthal contribution is somewhat controversial, and if any of us have it, it's not just Europeans; and (2) some of us appear also to have genetic input from another hominid, Denisovans.

But to your broader question, of course there are people motivated by insidious ideologies who view multiregionalism as a way "out" of having African ancestry, but not all multiregionalists are racists. There's a bit more here.
