I think of the term magic as applicable to any force not well understood by physics - e.g. gravity could be considered magic - but also most of psychology. Perhaps the point is nothing more than to baffle and disgust and terrify, for who would be willing to face off against those who would do such things?

I feel we've passed the point where the enemy is at the gates.
The abyss is already in our midst,
Its gaping maw consuming everything.
If you would prefer to turn away in disgust, I understand, however;
"Without debate, without criticism, no Administration and no country can succeed--and no republic can survive. That is why the Athenian lawmaker Solon decreed it a crime for any citizen to shrink from controversy." - JFK
