It depends on the elders in your local congregation.
I left the org in Oct 2001. Since then i have been celebrating xmas/birthdays etc etc. Been loudly vociferous in denouncing JW teachings at any and every opportunity. Discussed all my findings re UN/blood issue/JW v Bulgaria in European Court of Human Rights with my JW husband. Taken my JW husband to court to prevent him taking our daughter to meetings (I won by the way).
And still I have not been disfellowshipped.
My brother in law is the Presiding Overseer in the local cong - I stood in my kitchen last December (my house was COVERED in xmas decorations) and asked him if I had been disfellowshipped. "No" was the answer.
And I still haven't heard anything from any of them. No shepherding visits, nothing.
I don't know whether they can't be bothered, or whether they are scared because I will NOT be walked all over (and they know it), or whether it is because i am still related by marriage to the PO?
So I really think it depends on the attitude of your local elders, and how much grief THEY think YOU will cause THEM if they started to rock the boat.
Just my thoughts.
