He's wrong about coffee and refrigerators. It's true that some places tried to ban coffee due its stimulant effects, coffeehouses spread through Europe pretty quickly in the 17th century.
Here is the story for coffee. Coffeehouses were banned in Mecca from 1512 and 1524 before they became accepted. Then according to legend, opposition to imports of coffee lead to Pope Clement VIII being asked to ban it around 1600. He decided not to do so, and the rise of coffee houses came later. Then in both England and Germany, coffeehouses were seen as such places of disrepute that women were banned from going to them!
On refrigerators, early refrigerators used ammonia, which was toxic if it leaked. And early designs did leak. This lead to valid safety concerns. Concerns that were later addressed by the invention of freon. (Which is an unbelievably safe chemical for everything except the ozone layer!)
To be fair to our German and British friends, depending on how coffee was introduced (sailors/pirates), they may actually have been places of disrepute.....
The best source I could find is http://www.ijhssnet.com/journals/Vol_3_No_21_[Special_Issue_... which describes the condemnation of khat:
> Khat was cursed by God forever to be chewed by humans because of causing a divine displeasure when God came to Earth and all the plants bowed before him showing ultimate respect with the exception of Khat.
