There are many "orders" and societies across the world for different people(s) of historical significance. One such is the Order of Genghis Khan in Mongolia.
In this instance, Charlemagne is the "Father of Europe" and 60% of Europeans can claim descent from him.... and 41% (133 million) of Americans are of European descent while 61.6% self-identify as white (243.8 million). Not to mention the millions of people of mixed heritage. That is a lot of people! There is a huge chance that many in these groups are descended from Charlemagne!
I am a descendant of Charlemagne and these orders and societies have helped put in perspective the who, what, why and how Americans are connected to their European ancestors.
To assume that all of Charlemagne's descendants are white and racist is the slippery slope - if not the edge of the cliff. As a person of both Native American and European descent, I can say that having a society such as the Order of the Crown of Charlemagne do a huge amount of the genealogical "leg" work for my European parts, has helped tremendously. As Peter Joseph Forsling put it very well, "it isn't about racism, it's about genealogy".
Much of Native American roots are from oral tradition which takes much more time and patience (listening) to extract so I'm thankful for the help in other areas.
