Whites built the Great Pyramid in 2,600 BC. It was 481 feet high, as tall as a 40 story skyscraper covering 13 acres of land. It took 20 years to construct and consists of 2.3 million blocks of stone weighing 2.5 tons each. The mongrelized people of Egypt today could not build such a monument.
The Egyptians were very race conscious as seen here from this depiction of an ancient monument. From left, the blonde leader, next the Semitic Arab, then the mulatto with Semitic and Negro features and finally the pure Negro. Note that they knew that the Negro cannot grow a beard!
