Like I said, to me it's pretty simple:
- If you join a group, you should honor the group and respect its leaders and mission. You should try your best to cooperate and be a team player.
- If you can't do that, then politely leave the group with no animosity and find a group that suits you better.
- If you simply cannot find a group that suits you, consider that the problem may be you and not the groups.
- If you determine the problem is you and your attitude, make adjustments, go to #1 and repeat.
- If you decide that the problem is everyone else but you, consider yourself excused from having to assemble with others or cooperate with anyone to accomplish the mission of the church.*
