My jw says the same thing. He can't believe that anyone could leave simply due to it not being the truth and doctrinal issues. No, all you apostates want to do is go out and sin and drink, have sex, and generally be immoral. You can't handle living the jw lifestyle. If he ever gets his brain back I wonder what kind of condition it will be in.
The drinking and sex is what opened my mind to how hypocritical the witnesses are thier kids are some of the worst. Most of my worldy friends do this but they usualy leave home first and don't hide it as much from thier parents. Oh and they aren't pretending to have god's backing while hiding it.
