Abstoßungskraft is the moving force by which a material cause can act on any other to remove them, e.g. a repulsion force.

Gesamtkunstwerk is an artistic creation, as the music dramas of Richard Wagner, that synthesizes the elements of music, drama, spectacle, dance, etc. A universal artwork, one which makes use of all or many art forms or strives to do so. First used by German writer and philosopher Eusebius Trahndorff in an essay in 1827,  Wagner used it to describe the Attic Tragedy. (Thanks, Wikipedia & Dictionary dot com)

Volksverhetzung is a concept in German criminal law that bans the incitement of hatred against a segment of the population. You are guilty of this act if your acts are deemed to incite ‘hatred against segments of the population or call for violent or arbitrary measures against them’; or ‘assault the human dignity of others by insulting, maliciously maligning, or defaming segments of the population’.  (Thanks, Wikipedia)
