Being a young, school aged child in the 80s the Watchtower had me scared to death of everything that went bump in the night. I was terrified of demons, demon possession, and demon activity. There were so many JW demon filled urban legends I felt like I was starring in the movie Poltergeist. Then there were the actual demon stories portrayed as true in the pages of the Watchtower.
Watchtower has always had a knack of making everything in life wrong, bad, or demonic. Pick any mundane thing and you're bound to find a JW somewhere that will tell you why said thing is wrong, bad, or demonic. Even more so if it is something that brings joy or happiness.
