A lesson from history from your local crystal shaman (methhead):
once in ancient times the scythians had a period of very long periods of war, to the point that the men spent much of their lives in foreign lands and didnt see their wives for some time. when they returned, they found that their jerry slaves had knocked up all their wives and the scythian sons had been replaced with bastards of mixed heritage, since the slaves were from the conquered tribes the scythians warred against. the scythians resolved themselves to slay every bastard, and the slaves, and the women, whom they gave the especially disgraceful burial by throwing them into lakes and rivers. the slaves and mutts they left to the beasts. the scythians then raided greece and stole many of their women, and took them back to scythia, and from that their race was replenished after years of the bastard wars.
