The RH blood type is more likely an indication of something other than the 15% of human population mentioned by Cliff & Pete with different DNA. The RH blood type is almost completely a european 'thang' and the impression I got was that they were talking about 15% amongst the population in general.
The RH negative blood type is often said to be associated with the Merovingian blood line. It certainly has some different characteristics. Wouldn't an 'RH group' already have this all figured out?
Someday I will find out what my blood type is. But I am certainly within the 15% that 'cannot be brainwashed' as Cliff. I'll admit to having been a little bit brainwashed (brainrinsed?), but snapped myself out of it with help from traumatic events. Frankly I am surprised the figure talked about (15%) would be so high. Perhaps they are not the loudest members of society?
