Why conservatives hate slime-made antibiotics

People whose personalities are fearful, distrusting and easily disgusted (and who thus tend to think, act and vote conservatively), held up the development of naturally-made penicillin for fifteen - wasted - years between 1928 and 1943.

Chief among them : Sir Alexander Fleming and Sir Howard Florey, both who thought the stuff was best left on the shelf, until it was 100% man-made artificial.
