Elisabeth Shorten (Readers' Forum, Sept. 17) says that "it's good to be able to read articles that I consistently agree with." Her statement reminds me of that old saw, "if there are two of us in a room and we always agree with each other, one of us isn't necessary." There is also a danger in reading things you don't agree with: You may find out that you're not right and have to expand your perspective.
