Dude... your story starts as being df’d fir not having your camera on. When questioned you admit to fornication.
You can lie to us, you can lie to the congregation, hell you can lie to the desert god, but i hope you learn not to lie to yourself. Self honesty, self awareness, being able to see yourself objectively, these are some of the greatest gifts a man can have.
He has every right to be annoyed!! Don’t be so high and mighty!
Even by Witness standards it’s extremely dodgy to use the fact of someone’s camera not being on/possible technology failure, as the measuring standard of a persons commitment to God or spirituality!!!!!
It’s obvious English is not his first language and he clearly said they claimed he was not repentant enough to be reinstated, so he was effectively disfellowshipped for “attitude” rather than the particular sin.
In fact everyone is DF for their “face not fitting” or not being related to the right people, etc, since we are all DF (in theory at least) not for the sin, but whether we are “sorry” enough.
He may have many reasons not to want to be DF we all know that, As MickBob said, use their 2 witness rule and admit to nothing!
