BTW I was only disfellowshipped because I did not show a repentant attitude over admitting to occasionally getting drunk
Same thing they told me. Got drunk once, smoked once, had a girlfriend. They said I wasn't repentant, and DF'd me for that, not for the actual behavior. I didn't appeal, my roommate got DF'd because he was my roommate. He wasn't doing anything wrong at the time (that they knew about) they just DF'd him because we lived together when I got the boot. He appealed and lost.
Your DF story reminds me of one my dad was involved in. He was was on a committee that sounds similar to this on the western side of Michigan. They had called in elders from other congregations because there were other elders involved in the situation. He was proud to have done his duty. I don't know what the fallout was, it was from a town north of me, one that seemed to have more fun than our Congregation did.
Anyway, it seems that a lot of times they DF somebody just to make an example of them regardless of the severity of the "offense". Odd that the WBTS wouldn't step in for you, just let the locals run the show.
