Another option for those who can stomach the fading/faking route (it takes acting skills and putting up with being pressured back for quite a while), another option is to quit any and all activity abruptly.
Politely but firmly decline any meetings with elders.
Tell friends and family nothing unless they initiate the conversation and you're absolutely sure that the conversation will stay absolutely confidential. Otherwise you could tell them something along the lines of 'After careful/prayerful research/meditation I have concluded I can no longer in good conscience preach or attend meetings.'
This method has less negative effects than disassociating as people are at least allowed to talk to you. In practice many dubs will avoid you anyway. This happens when you fade as well, but it takes a bit longer with fading so that may be easier to adapt to.
