You read of those heart warming stories in the magazines, in the books, and hear them over and over again from the platform, yet, when you look around, you fail to see it.
This is one way the WT gets away with it. When you don't see the love, and you won't, you conclude it must be something wrong with you, or with your local congregation. But you never quite make the leap to conclude it's an organization-wide problem.
Since Jesus said it was to be an identifying mark of true Christians - as since genuine love it is generally absent from the JW faith you can see that they are NOT the true religion. You don't need to get bogged down in doctrinal discussion - this reason alone disqualifies them.
