I think you need to research the etymology of the word "racism;" where it comes from, how it is used and what it really means.
You are asking the right questions, but one of the continuing problems is that at the foundation of every man's thought and reason are pre-theoretical axioms which represent essentially religious commitments, even if not formal or doctrinal; they may be Christian, pagan, animistic, humanistic &c. They are presuppositions that a man holds that are basic truths he accepts, whether they actually true are or not, and to question them is absurd. The problem is that very few people engage in the hard work necessary to become epistemologically self conscious - in other words to know what their pre-theoretical axioms are and whether or not they are rooted in truth. In turn, in attempting to discuss issues like authority, politics, God, sociology &c becomes wasted effort because those involved in the discussion don't have the philosophical tools at hand to resolve the issues and once they run counter to the other persons pre-theoretical axioms you are then dismissed as ignorant, retarded, incomprehensible, morally degenerate &c. They don't understand epistemology, what they know, why they have knowledge and worse they don't know what they don't know - what their pre-theoretical axioms even are.
Consider India and the caste system, outcasts accept their lot in life, it is a self-evident truth - a pre-theoretical axiom of that society and Karma rules through re-incarnation. People born in the lower caste don't try to better their position in life because they don't believe it is possible, and those above will not allow it either. Consider Nazi Germany, it's essence was not totalitarianism even though that is what we have been taught; rather it was a new racial foundation of society. If that could have become the ideal and common assumption of the society the totalitarian methodology could have been relaxed. Our citizens don't trouble their consciences about the execution of Nazi's and their sympathesizers at Nuenberg because they held to wrong and treasonable beliefs. The same holds true for our Civil War, it is extremely difficult to engage in any profitable discussion about reality because it is presupposed as true that slavery is evil and brutalities that did exist are presented as being universally true. Reality is a stark contrast and you can't point out the truth that two centuries of social progress occurred for the African in a three month boat ride. No, it is believed he was a nobel savage and taken from a free and self-directed life, there is a reason for that belief even if not factual that is rooted in philosophy.
Our society is founded upon self-evident truths consistent with it's pre-theoretical axioms forming the ethics of society; the descendents of humanism of the European enlightenment which is a competing religious philosophy grafted into the American populace, however, have completely different beliefs and demand disestablishment of the existing order and replacement with theirs and they are willing to engage in whatever political, social, economic or violent warfare is necessary to realize their goals.
Every culture is a theology realized and has self-evident truths consistent with its pre-theoretical axioms and none can be tolerant of assaults against it's fundamental self-evident truths. It can extend tolerance to opinions and beliefs peripheral to its foundation without suffering collapse and in peaceful times may temporarily enjoy questioning of its central fundamentals. But when that grows more than questioning and becomes subversive then a defense follows and the dogma's are enforced and the greater the threat, the more rigid the defense.
In every society, though, political liberalism begins as theological liberalism, not the other way around. Anyway, I could go on to hash out a brief analysis of this in our country to get into the roots of racism, but I'm out of time. If you want to continue the discussion I'm willing, if not that is ok as I understand most are utterly bored by discussions they don't perceive as practical. A good exercise would be to peruse this recent
thread on the civil war which has some very good material in it, but attempt to do so dispassionately examining the statements and discussion of participants attempting to understand their presuppositional beliefs instead of the content of their conclusions, the former determine the latter. If you can do that it will help you be able to put the present issues of social conflict into a context for more thorough analysis.
Cordially,
