Question posed:
[[ Spiritual atrocity - What is Racism ? ]]
"Racism" is a fabricated word from the left (actually, first used by Marxists) purposely crafted to be used as a tool to attack, silence and repress whites and by which to dissemble the established social order.
I challenge you to take a moment and search earlier versions of Webster's Dictionary online.
Example:
Search the 1828 version of Webster's for "racism":

Does this surprise you?
How can this be?
The reality is that up until around the 1930's, when Marxists introduced "racism" into the lexicon, the notion that people would prefer to associate with others who were "alike", and distrust others who were _not_ "alike", was considered normal and acceptable (indeed, preferable) human behavior. As such, it was accepted as the natural order of life itself.
"Racism" (as the term is used today) was in fact the established policy of The United States -- which maintained immigration policies that severely restricted immigration to [mostly] those of white/European heritage. Of course, this was to maintain the ethnic/racial makeup of the nation to be what was traditionally considered to be "American".
It's only since the rise of marxism in America, as embraced and espoused by the left, that "racism" has gained a foothold in the language. The white conservative who responds to an accusation of being "racist" by answering "I am not a racist" has lost the intellectual and the emotional argument simply by virtue of his defense -- because the accuser has at that moment won by changing the nature of the argument from the original subject to the other person.
The only way to overcome the phony concept of "racism" is to ignore it, and to be bold enough to promote the natural origins of human interaction and behavior. As they were before the marxists conned Webster into entering the "R-word" into the dictionary.
