There are several such groups that are around, and by searching, I am sure that you will find one. In fact, very few groups are like the WTS in that they lay down the law to everyone in the fellowship, on pain of expulsion. Thess ones are cultic, and to be avoided.
However, do not be disappointed in that there is no group that permits TOTAL uncorformity. Every fellowship, like ours, which is Baptist, has at least a base list of teachings which are not negotiable.
These may for instance either be Trinitarian, or Unitarian. [I am unaware of any fellowship that allows both doctrines, except enlightened ones like JWD]
Charasmatic or Non [ie tongue speaking, or not] There are a few who don't make an issue of this, but these are rare.
The Integrity of Scripture. [ie there will be those who teach that the Bible is inerrant, and those who will teach otherwise]
But other than this there is a wide divergence of opinion granted an individual to interpret Scripture according to his/her leading
Good hunting
