This is very well said. When one is looking for the local church where God would have one serve, one should become familiar with a church's statement of faith first of all, then any other governing/procedural documents. If one sees any "hill to die on" disagreements, one should not join that church - to do so will almost inevitably lead to dissension among the members. If one finds things with which one disagrees but can live with, it's up to one's conscience whether to join, but if one does so, one should not make an issue of said things.
It's extremely unlikely that one will find any church where one can agree 100% with everything. If I had written those documents and looked at them some time later, I'm sure I'd disagree with myself! Therefore, joining a church (which I see as biblically correct though I cannot cite a rock-solid proof text) will mean giving up a portion of one's personal liberty. There's scriptural precedent for that - it's what Paul meant when he talked about becoming all things to all people. It was relinquishing some liberty so as not to offend, thus costing him a chance to witness for Christ.
