As someone in a similar situation, having grown up in this type of church and left for the same reasons - I can tell you from experience that (with maybe the exception of your own family) they will not notice that you are gone. Instead, they'll write you off as lost, or a cast-off. They'll focus on recruiting to replace you with someone who is less trouble and more submissive. I do think that is backfiring on many of them as we see with the dwindling numbers, but their pride and pursuit of power will never allow them to worry about those of us who simply stop showing up. To them, we're now one of the "others," not worthy of their services or their concern because we no longer submit to their authority, power and control.
