Deletion of Walt Brown (creationist)

Comment: I don't buy this idea that "long term" this person will be less notable. How could we possibly judge this in an objective way? The whole idea reeks of |crystal ballism (yes, I know that's not the intended use of the policy, but its spirit certainly applies here). If we adopt the notion that at some point in the future a currently notable subject might somehow become non-notable, then we might as well delete ''every article'' on Wikipedia since this is true for all of them. I see no other reasonable grounds for deleting this article
