2. Where do Negroids fit in?
They are prehuman or subhuman. The Bible suggests this. So does science.

The Bible does not support the
idea that Adam and Eve gave birth to all the different races on the
earth, but rather implies that Adam and Eve were a separate creation in
the midst of other people who existed prior to them. Since these
subhuman people existed before Adam, they are called "pre-Adamic."

4. Are we called to hate the Negroid?

No, they cannot help being born subhuman. It is like hating a dog for
being a dog. Negroids do commit crime at very high levels, but that is
because like all other animals, they have no soul and thus no
conscience.

5. What does science have to say about Negroids?

Evolution is a myth. However, we can also argue from their standpoint
that Negroids are subhuman or prehuman.
Scientific evidence also proves the Negroids are prehuman or subhuman.
Fossil evidence indicates that negroids have been around for at least 3
million years before the humans arrived. If you are into evolution, this
is a chart for you to examine
