I could explain the purpose of inbreeding and it's historical roots, but I don't know if I have the time or energy to get into the details. It originated with the House of Judah and the Mosaic laws. It started out as a means of tightly controlling the Jewish people and using them to pursue their agenda to rule over mankind. They had to loosen the original laws when inbreeding led to the problems that inbreeding causes, so they began to selectively introduce outside bloodlines, mostly those of other powerful family lineages, always for strategic purposes. The tradition has continued over the millennia, until now we have a number of powerful elitist families who are all in league and use the same basic method of control in order to continue with the same agenda for world domination. This is part of the reason why people get confused over who is behind the NWO. All of the elitist families today are connected through marriages within this tightly held Jewish cult, even if they don't claim to be Jewish, and usually don't have more than a tiny fraction of the original DNA of Judah, if any at all.
