"He believes that many jw's leave because it is hard". What does he base his belief on. Can he give you some examples of those who he knows left for that reason. What he believes is not what matters. What matters is that millions have left for whatever reason. Is he aware that many have been abused, disillusioned, lied to, families torn apart, these numbers far out way any who leave because it is too hard to measure up to Watchtower standards. For some it was harder to leave because of family members still in. For some it's harder to stay because they don't want to lose family and friends, so , they go through the motions.
