Very well stated. Steve2 also makes a very good point that is often overlooked: A person's impression of what "makes sense" religiously or what the true religion should be like, is heavily biased and shaped by the religious values that the person was brought up with early on.
That's why the JW's criteria of what constitutes true religion are all based on JW interpretation of the bible. Is it any wonder that it always ends up painting their own religion as the only true religion? That's why Muslims will always think that polytheistic religions make no sense - they're judging such religions by the acquired value of monotheism which they learned from Islam.
So without realizing it, religious people are engaged in a kind of circular logic by judging what constitutes true religion by using criteria they learned from their own religion, which means they are implicitly presupposing that religious values learned from their own religion are objectively true, when they should in fact be questioning it. Psychologically, it's a virtually impossible task for a religious person to objectively determine what is the true religion free of any biases acquired from their own religion.
Only someone brought up without religion is in the best position to objectively determine which religion makes the most sense, free of any theological biases implanted in them by a "native" religion.
