I AM STRONGLY convinced that as long as children continue to be brought up to learn behaviours and imbibe ideas that certain groups of humans are inherently worth less than others, we can expect human civilisation to not be much more than an exercise in Damage Control.
I am also convinced that attitudes of superiority—if they did not stem from feelings of insecurity, which they often do—sooner or later cultivate fear vis-à-vis those one dismisses as beings not worth the respect of a peer and a fellow human being. This fear may guise itself as disgust and aversion, mainly because one is guilty of metaphorically throwing the first punch whenever one thinks of others as being inferior through no fault of their own.
