Virtually all JWs will say they are repentant. A more accurate statement would be this:
"If, however, a baptized Witness commits one of the 27 or so 'bad' acts listed in the JW elders manual and gets caught or confesses and is not able to convince 3 JW men that they are repentant, he or she will be shunned."
Haha, and that, of course, is what I call a politician's answer
Raven was questioning the actual act of 'shunning' and not the reasoning behind it.
Contrary to what Raven evidently wanted to imply, the WT is up front that it does shun former members who have, in their view, unrepentantly sinned in some way. The FAQ, as would be generally accepted for a FAQ, gives a fairly brief but fulsome answer without getting bogged down in all the intricacies of various situations etc.
Thus the bottom line is that the WT is clear that it will shun former members in certain situations.
Yes, you can take issue with what those 'certain situations' are, and if it's fair or even scripturally correct etc etc, but that doesn't change the principle of the act of shunning that the WT says it does do.
