Thank you!
I came home from Grinnell last May or so to get my wisdom teeth out, and decided to set up an appointment during his 'office hours' to try to set Johnson straight about how totally unscientific 'scientific' sermons are and if he HAD to babble about creationism he should at least make it clear that he has no idea about science. A letter to the newspaper (reaching a broader audience) seems like it would be more useful.
