The ability to demonize an entire species or tribe is a particular attribute of humanity. To formally infuse a tradition of brutal savagery against another group or species peppers the history of every nation and is sometimes the very reason new nations are founded. Blood feuds, discrimination, outright lies all have their place in this disgusting history from denigrating the intellect, attributing vile nefarious reasons for behaviour, and without any proofs attributing aberrant behaviour to entire populations. This ability to devolve ones faculties to unthinking hate-unto-murder is the lowest form of humanity.
It is, in fact, no humanity at all.
