I am often frustrated by arguments from silence. The following quote is an example of what is, to me, bewildering logic. The topic is the dating of James and the author would like to argue for an early dating by James the Just himself:

James’s lack of any mention of the destruction of Jerusalem in A.D. 70, though an argument from silence, does seem to support an early date. The destruction of Jerusalem was a highly significant event for the Jews. James, a Jewish author, writing to a Jewish audience, the twelve tribes who were dispersed (James 1:1), and writing a letter with Jewish concepts, would likely mention the destruction of Jerusalem, especially if he was writing after the city was destroyed. If James wrote after A.D. 70, some of his readers could have been present at the destruction of Jerusalem.

The letter of James also does not mention the life, death (possible and debatable exception is 5:11), or resurrection of Jesus. Presumably the author is writing after these events, which would have been important for the author’s audience. It seems to me that the life, death and resurrection of Jesus are quite a bit more relevant and more likely to be mentioned by the author than the destruction of the Temple in Jerusalem. By the way, Jerusalem itself was not destroyed in 70 CE, but the Temple was.
