Thankfully, I haven't seen the claim of "junk science" for quite awhile. "Junk science" is a contradiction. If it is "junk thinking", it is not science. If it is science, then it is not "junk thinking". It was often used by the "right" to disparage results they didn't like.
Now it is used by Jim Hightower as a disparagement of someone whose views he doesn't like: "Todd Akin, a devout worshipper of junk science, is a member of the House Committee on Science." See "Welcome to the GOP's Theological Nutland", Jim Hightower, 2012-09-04. Todd Akin is the politician who claimed the bodies of women who have been "legitimately raped" can protect them from becoming pregnant.
It just occurred to me that some people's theological thought has nothing to do with God or with logic. It is more hubris telling God what they think he or she should have done or should do.
