wontleave...Not trying to be argumentative or anything....just curious how you concluded this.
Most are thrown out for allowing their trashy personality to get the best of them and lapsing into totally unacceptable behavior.
Subjectivity of "trashy personality" aside, I think "totally unacceptable behavior" might be a stretch....even if we use the jw yardstick of acceptability.
That's because they are constantly manufacturing sins. It's just like the Salem witch trials. There is a sense of relief, superiority, camaraderie, and fear of leaving every time a witch is hung. It's what keeps the congregational culture alive and together.
For example, I was deemed unfit for being in my sister's wedding party because I was allegedly seen smoking. I had not been smoking. Someone made that up just to be petty and spiteful.
I know a handful of ex-jws who were disassociated at age 13 for unfounded accusations of fornication and drug use. [DA is what they did at that time for unbaptized members.] I could go on....
So subtract the manufactured sins.
Subtract what is generally acceptable behavior, miscategorized by the wts.
We're left with "some".
