As I read more into the concept of race as a science, it appears to be based not on Catholic theology, but on reformation era ideas, the Enlightenment and the Protestant revolt. The work of Christoph Meiners comes to mind, and his ideas can be seen as precursors to Traditional Guy 20's own ideas on race.
I do not take my understanding of my neighbor from a heretical thinker as Voltaire, or from Franz Boaz, but from Holy Mother Church. You should read up on your faith, and spend less time on the myth of racial purity and superiority.
Nice on ignoring everything I said. I will ask yet again do you consider Blacks superior in cultural ability to Germanic people or Japanese?
Your question does not change the fact that race as a science is influenced by non-Catholic and anti-Catholic ideology, and is not based on the teaching of Holy Mother Church.
Every culture has something of value to offer. Some cultures have a greater impact on history than others. Many factors are involved in a culture's historical impact and longevity. Religion makes a greater impact on the benefits of a given culture than does "race". A culture that is firmly rooted in the Catholic Church is superior to that of any other culture.
A good and holy Catholic of mixed ethnicity is superior to a supposedly "racially pure" Atheist or agnostic. The Catholic culture of mixed ethnic origin is superior to that of a culture of "racially pure" heretics and pagans. Therefore, it is entirely possible for any given African nation to be culturally superior to any European nation.
Archbishop Lefebvre's work in the country of Senegal showed the cultural potential of the people of Africa. This good and holy work could have led to a great awakening in that part of Africa, but the forces of evil are hard at work to destroy Christ and His Church.
The problem with American culture is not racial or ethnic mixing, but the loss of the faith. This is where the true battle must be fought. Race is a diversion from the true fight, which is a fight for the salvation of souls.
