This is a typical cult minded response and reveals a lot of pride on his part . He is saying that no decent person could ever honestly disagree with Me over My choice of religion , because if I say it is the truth, then it is - period. Only a fool or a wicked person would want to leave.
Actually that is the gist of that brochure they printed for the inactive . If you have gone then there is something about you- Anxiety, depression, falling with someone etc.
I can honestly say that I only left because I got to realize that:
1) the people of "the world" that I knew through work were just ordinary hardworking family minded folk and I could not see that any God worth worshipping would slaughter them like beasts ,just because they had not joined the WTS
2) Time was marching on, they had already changed the generation explanation of Matt 24 once, I could not see how an "end of days" prophecy movement could span 3 centuries . When we approached the last millennium I knew something was amiss.
I had some problems with the congregation as it happened but that would not have shaken my faith in God or the worldwide movement.
