First, you are changing the subject, which is "bad science." Dawkins is clearly aware that bad science exists - and a common factor that makes the science bad is that it is non-science masquerading as science.

Second, you are purveying a common, erroneous apologetic in that you are conflating individuals with the activities in which they engage. To use an extreme hypothetical example to drive the point home: A person can be the world's greatest violin player and a mass murderer. That his music is beautiful does not excuse the crimes he commits.
