I was aiming for the “not having basic human morals” usage of the word, nothing more.
Webster's dictionary:
plural Negroes
1 dated, often offensive : a person of Black African ancestry
2 dated, often offensive : a member of a group of people formerly considered to constitute a race (see race entry 1 sense 1a) of humans having African ancestry and classified according to physical traits (such as dark skin pigmentation)
Note the "offensive" warnings. Now let's see subhuman:
: less than human: such as a: failing to attain the level (as of morality or intelligence) associated with normal human beings b: unsuitable to or unfit for human beings subhuman living conditions c: of or relating to a taxonomic group lower than that of humans; the subhuman primates
In the case of subhuman, Webster's dictionary does not give any warning. And there is no reference to any wars.
Don't try to make people say things they are not saying.
In this case the intended meaning was clearly:
"failing to attain the level (as of morality) associated with normal human beings"
I feel your pain, tho.
