This is silly. It tries to exaggerate Von Braun's single (and rather ill-advised) venture into endorsing the "two method" teaching in the California schools (at a time when it was still risky to talk about evolution in a straightforward way) as an endorsement of Creationism. The same article also claims George Washington Carver as a Creationist (and attributes peanut butter to him). It is clear he believed in a designer. I don't understand your point. A brilliant scientist who believes in the God of the Christian Bible. Simple.
Why must the messenger by torn down, when the point is straightforward and obvious?
