Anytime you set foot in a KH and attend meetings and are counted while being seated you are in effect preaching this BS by your actions; you are in effect showing others around you that you endorse this bullshit weather you are going to keep ties with friends and family or not.
No you are not. The only people that care if you are at the meetings or not are Witnesses. It's perfectly possible to be disengaged from the meeting and refuse to participate. People do things for the sake of others all the time and it's simply not possible for all to simply stop going regardless of the consequences.
Participating in field service is a different matter in as much as the point is to engage with the public. I had got my participation down to all but zero, simply sitting in the car once a month whilst my wife posts some mags through old route calls. I've just had a difficult conversation with my wife about that after pushing to the next level of not going at all.
The path from being a Witness to an ex-Witness is not some moral crusade where an individual is obligated to shout their disagreement from the rooftops. Some people may never be able to get to a point of open rebellion. So what?
For some, part of the necessary process is to completely remove themselves from all links with Jehovah's Witnesses and this may be at significant personal cost. This does not mean that this is required for all those awake to TTATT.
The biggest difference between being confined by or free of the mental shackles of a high control group is the freedom one has to think for oneself. Part of that freedom is also giving others the right to make their own choices without it always being a black and white, right or wrong, moral or immoral, open and shut case.
