From this board I have ascertained that the elders' attitude to the "sin" of apostasy varies enormously from place to place. Around here they seem pretty tolerant unless you actively seek to spread it around. I had no cases to deal with in 24 years as an elder. However, I learn that elsewhere (in the U S it seems) committees may be formed if you express thoughts in a shepherding call.
I would not risk it. Keep quiet. Make an excuse to fade away, [depression, stress, having to work long hours etc....] After all, it would be very easy to pin this on you.
2 John 7 -10
....."Persons not confessing Jesus Christ as coming in the flesh. This is the deceiver and the Antichrist. ...If anyone comes to you and does not bring this teaching never receive him in your homes or say a greeting to him.
That sounds hard , but that is how they are trained to think by the WTS.
