Why do members of Christendom claim that Jehovah’s Witnesses have made false prophecies, when we never have?

A prophet who is "uninspired"? Get a life. I was a member for 39 years, all through 1976. Everyone was in expectation of the predictions that would shake the earth. I also lived near the beautiful mansion in Kensington, San Diego, called "Beth Sarim". That "prediction" was for 1925 I believe, and it also did not materialize. The date associated with the "invisible" presence of Jesus of 1914 is the only date that witnesses have for their salvation. I do not need a fabricated date to substantiate my salvation, I have Jesus.
