Racism is a manufactured concept created by individuals that considered themselves to be superior because of certain physical characteristics they shared and to exclude individuals they considered inferior because of certain other physical characteristics. Color, size, shape, hair, eyes even some genetic differences do not indicate different races, just differences. The idea of there being different races of people is fundamentally incorrect and antiquated at best and now only perpetuated by those that consider there to be benefit from the concept or still feel somehow superior and therefore need the concept to prop their misinformed, baseless ideals. Don't take my word for it. Look it up in Britannica (or your favorite source for actual facts) or here:
Notice the statement in the first paragraph "the concept of distinct human races in a biological sense has become obsolete".
Of course there are still those that reject logic and fact and hold to the idea that Wikipedia and other undeniably accurate sources are liars or put forth by those few dozen that want to deceive the masses to take control and rule the planet.
