There's a balance to be struck here between right doctrine and being rightly related to one another.
Good doctrine and "rightly" relating are not opposite sides of a spectrum.
They are related because the peace, purity and unity of Christ's church are based on common confessed doctrine, as a basis for worshipping God in spirit and in truth- that provides the basis for relationships on every level of Christ's church.
I do often see a good deal of uncharity in the PCA, particularly on the blogs. If you want a smaller tent, the PCA is not for you.
Not sure what is meant by this,
the tent is a biblical reformed denomination with presbyterian government-
"Faithful to Scripture, True to the Reformed Faith, and Obedient to the Great Commission."
The tent is always attracting believers based on whom God will call. It is not a tent intended to be all things to all people.
There's a set of essentials, but apart from those, the PCA is (by intention) broad in its interpretation of the confession.
There is no "set" of essentials-
that might be said for the church universal, but not for our denomination (or any denomination).
The Westminster Standards and Book of Church Order are the constitution, the former measured by "every proposition and/or statement of doctrine [therein]. That is secured by sacred oath, so it's not a negotiable.
I'm surprised that anyone's really surprised here.
There are many good things going on in the denomination, that God is doing through it, to the end of His Honor and His Glory- it is focus on that provides peace and unity, just as in the many apostolic admonitions to the early church.
It never has been about bureaucracy or institution, something for all of us to constantly and prayerfully keep before us.
