Good to see you have not completely missed the boat. Connecting with your folks is the wisest thing you could of done. You are going to avoid a lot of regrets, and be able to show wife and in laws you are maturing into a real father yourself.
You have perfect timing here. What you watched going on in Australia is a game changer for the WTB&TS. From my perspective 2013 was a turning point for the Organization in many ways but all the different moves they made centered around the molestation issue. The point everything turned on was a lady Candace Conti, nothing has been the same since she broke the molestation barrier.
My input would be relax do not think you need to make any major stand right now. just key into your father in law. Even he a long time elder should be growing apprehensive as to the money moves being made at a time when he was expecting the "Great Tribulation" . Watch him close! Hopefully he was from my generation who came through the 1960's and is a solid man. If he starts questioning, then he will be open for discussion of issues raised in Australia. You could very well have some interesting conversations. Your connecting with your parents is will demonstrate a maturity on your part.
I had a couple of people tell me that the Watchtower don't even try to enforce the shunning of families in the LA Ca. area among the Mexicans. Mexicans DON"T shun families! May by they know something the rest of us don't know.
