I see the discussion on Evolution/Creation as a means, not as the end.
A long time ago, I decided that JWs follow whatever the WTS says because of who it claims to be, regardless of what it says. So my focus has ever been to sever that mental strangehold.
With chronology, my focus was on showing that the WTS lied, that they therefore did not deserve a JW's trust. Likewise with blood, I checked the 102 citations in "JWs and the Question of Blood", and I was able to show that they were deliberately deceptive in the way they cited their sources. And this was literally a matter of life and death.
So it is with evolution/creation. Rather than focus on "which is correct?" the focus needs to be on "how does the WTS handle its sources?" When the WTS is shown to be totally untrustworthy in that regard, a JW must decide whether they should continue following a leadership that treats truth and them with contempt.
I know this is not easy, given the personal impact on personal relationships. This, of course needs to be weighed against the mental stress caused by cognitive dissonance.
