Racism (from a moral standpoint)

[MangaD]

There are many variants of the definition of racism, but I will go with the one from Wikipedia which best describes the origins of the term:

Racism is the belief in the superiority of one race over another, which often results in discrimination and prejudice towards people based on their race or ethnicity. As of the 2000s, the use of the term "racism" does not easily fall under a single definition.

From a biological perspective, racism appears to make sense. For instance, negroes are superior to other races when it comes to withstand the sun. All races appear to have something that they are better at (or worse at) than other races, with IQ being the most controversial in the scientific community and society due to the implications it could have.

Although, from a social perspective, racism is seen as inadmissible in public discourse. I wonder, is this wise? Should we completely ignore the biological facts of humanity and pretend that they don't exist? We live in an era where migration and miscegenation are more casual than ever, where millions of years of evolution are being undone as if they did not matter the slightest. Naturally, in due time some races will disappear (eg. red hair) as they will be overwhelmed in number and new mixed races will be formed, but this is not an environmental consequence, rather human fabrication. The same applies to the advance of medicine which allows bad genes that would naturally be disposed of by nature to artificially survive.

What are your thoughts on this?
