It’s disappointing that in the 21st century, that there still is so much racism and prejudice that we still see and feel today in most western nations, of which, we should really know better. The first part of why there remains so much implicit and explicit racism, for example, in America, comes down to the disappointing lack of knowledge displayed by so many of the favored race, and thus then their overall ignorance which thus leads them quite often to becoming racists in their viewpoint. In other words, those that are of the favored race and are poorly educated, are going to often lack the capacity to do the research, to think for themselves, and to cogitate, so as to understand better what racism really means and what it is all about. The second part of racism has an awful lot to do with the hierarchy that America has represented historically and still basically represents, in which, those that are of the favored race are basically confirmed through our educational system, to be essentially the master race of America, and thus all other races and ethnicities, are hence no better than second best or worse.
That said, to add further fuel to the fire, of racism, it is of fundamental importance to those that are racists, to find an avenue that makes sense to them, that will thus belittle the other, dehumanize the other, and marginalize the other, so that it would appear to these racists, that their racial position, makes logical sense. That is to say, to fairly judge another of the unfavored race by their actual merits and capabilities, along with keeping in mind other pertinent considerations that are relevant to this very thing, is never something that racists are going to be prone to considering, because that actually might make them be open to changing their mind, or adjusting their opinion, which they are wont not to do. Rather, their preference is to find something that is common to a particular race and not such of their own, and focus almost exclusively upon that, in a way and manner, which dehumanizes the other, by making the other appear to be less than human, and thus more akin to an animal, of which, those that are thus considered to be animals, are thereby categorized as being under the rightful dominion of exclusively those of humankind.
So too, to dehumanize the other is necessary for racism, because once it has been determined by racists that the other is not human, pretty much anything goes in the treatment of those that have been dehumanized, no matter how diabolical and evil those actions subsequently are. In truth, while most people can indeed be reasonable most of the time, we do so find, that when their blood is up, that they then are also quite capable of committing the types of acts, that no sane person, would ever consider doing, all done, with nary a second thought. In short, to eliminate racism, the dehumanization of the other must first be eradicated, and until that has been accomplished and thus thoroughly purged from the minds of humankind, certain those of the favored race, will continue their racist ways, until the very end of time.
