So far, I've found two clear quacks who are anti NDT; one is splitting hairs on GMO v. 'traditional' genetic modification, arguing semantics Neil does not assert. The other is some dude who shows a bio...from a movie site...referencing Tyson's bio on it that lists him as an...actor...which, in context of the movie site and his work in a few flicks would follow. He's trying to assert that Tyson does not have a BA in Physics, masters in astronomy and a masters in astrophysics' all easily provable facts.
So, the kook-iverse holds some non fans, it seems.
