I did not see a reliable demonstration of this, whereas I offered a number of quotations from a search for 'negro' & 'definition', demonstrating that the word, negro, is indeed offensive in all definitions, given its previous use, and it's apparent that those who use the word, negro, hate blacks and/or people of color. (I'd be surprised if you claimed that you genuinely don't hate or dislike blacks.).

As I said in the very next sentence it is a scientific term to describe a racial group of people. This can by itself not be an offensive word. I reject any of your definitions or quotes. I care about what I think and what you think, not what someone else might think or do.
You are literally on the most far right debate space that I've been able to find, so if we are not using the word in an offensive manner, then I really wonder which group it is you mean that is using negro as a negative term.
It is like saying you shouldn't call a dog a dog, because someone might use it in a negative context. It doesn't make the word dog negative... It is simply what a dog is; a dog.
A negro is simply a negro. Is it really negative to be negro!? Do you claim this? Can you not see how insanely racist it is to say that the term negro is a negative term? It is their fucking racial identity for gods sake, sorry for the language but I tend to get heated.

I don't hate or dislike "blacks". Others in the alt right might, but I think they are misguided. I unironically love diversity but I completely reject and hate LIES and DECEPTION; political correctness - fake politeness.
Black is a misleading word, which is why I don't like that word. It has poor scientific utility. It is used by liars to deceive the low IQ masses, because it makes them think of races as skin color, which is simply not true. You can literally have white skin and be "black".

This is very difficult to discuss because the Jewish US politicians list themselves as 'white'.

Yes, this is another way for them to marginalize whites. This allows them to take up white spots so that it looks like whites are well-represented, while they aren't.
Take the Biden administration. Out of the 25 mentioned on wikipedia, 5 are whites and 7 are jews. It looks like 12 are "whites" which is around half, so from the naive look whites don't look to be particularly underrepresented, but a closer inspection shows that they are only 5 out of 25, while they ought to be many many more with a fair representation.
