Thanks for taking the time to post responses guys! I apreciate it.
I know what you're saying about shaking someones boat. It rarely goes over well. And its important to look at the big picture. You don't want to win the battle, but lose the war.
I've basically taken that position until now. I believe a couple of things have led to my recent change of heart.
One is the time factor. Mom and dad may not have much time left. I would love to fully explain to them why I did what I did. I'd also like to have an open repore about why they chose the JWs in the first place, see if we can compare notes, or at least be at peace about the difficult life they chose for the family.
Another reason is the future. I know they were a major influence on us kids and the direction our lives have taken. I believe our concept of the Witnesses is closely tied up with them. Once they are gone, I fear that only a kind of rock-hard 'folklore' will be left. Any chance at having them influence the rest of the family with a frank discussion, not a WT filtered version, will pass. The family seems to be gradualy drifting apart. I can only imagine what my nephews are being taught about me at meetings.
A third reason is my peace of mind. I've noticed some negative things in myself that must have sprung from my family and being a Witness. I feel like getting to the bottom of it includes having an open discussion with my family.
Finally, the more research I do on sites like this, the more concerned I get and the more I want to get them out.
