Actually there have been people on these threads ranting against medicine and surgery. Not that the practice of medicine is perfect or saintly, but the rants imply that medicine itself is the work of Satan.
I am not exaggerating this.
I am not surprised.
On an HIV thread, there were several luddites who were spinning flat-out lies:(1) that HIV had not been isolated (not only has it been isolated, its DNA has been partially decoded); (2) AZT (AIDS drug) causes AIDS --- which does nothing to explain those who died of AIDS before its discovery or in Africa where it is seldom found . . . etc.
And, like some (again, some, not all) of the the YEC babble, it superficially sounds reasonable.
Of course, good lie sound reasonable.
