I selected three JW friends who I viewed as open-minded (1 active, 1 inactive, 1 semi-active) and carefully shared some of my key findings with them. I stated that I was happy to share more with them, if they were open to it. All three declined.
I brought 607 up with an elder and his immediate response was - oh, you mean it is 20 years off. He knew, but still teaches 607 from the platform.
With another elder I brought up the many misquotes and misreprestations in the Creation book and other WT publications. He was well aware of this, regretted it and said that I should leave it to Jehovah to hold them accountable.
These examples (and many more) show me that it is not to difficult for people to "leave the cage", but nearly impossible to get them to "leave the zoo".
Unless asked, I now remain silent. It is just like quiting smoking - you can tell someone how unhealthy it is, but unless they are mentally ready, they will not quit.
