That means that we not only were born-and-raised in this group, we are also very familiar with all things relating to the Christian belief system and the Bible. We quite literally lived the Bible; we know it inside and out and can quote from memory many passages contained therein. It has been my experience that most of us SGAs know the Bible better than most Christians. Many of us, including myself, are no longer Christian (here a distinction should be made: we never decided to become Christians in the first place; we were forced to become as such from birth). Thus, we generally do not like it when others take it upon themselves to "enlighten" us about God, the Bible, or anything related to the Christian belief system. We know everything about it and have decided it is not for us.
This is the bottom line! Firstly the CoG/TF was not "Christian", the life-style- of CoG/TF is NOT "christian" by any stretch of the imagination. In CoG/TF we were never taught Biblical teaching--we were taught a mish-mash of the odd scripture mixed in with Berg's revelations and perversions! If a person has "never decided to become "Christian" in the first place, then it seems that by asserting that they are "no longer christian" there is a contradiction, or a confusion.
One person "preaches" atheism, or hedonism, new ageism, or any other "ism" this is acceptable--however declaring Christ is wrong. It is fine to mock and use foul language at people who assert the bible, yet let a "Bible thumper" have their say--ooo people get all offended!
As for your assertion that "There are plenty of other forums where you are free to witness to whomever you please. ", you'd think. Most, so-called, christian forums don't want the Bible to be declared either as it threatens their cosy little set up!
I respond quite forceably to anyone who mocks, i'm feel sure you will have noticed by now.
