Then how would YOU decide the difference between major and minor issues, Aaron?In this post, you have set yourself as the arbiter of major and minor issues, of that which is important and that which is not.
My answer to the question is this: Yes, it really is that important that everyone agree.
What one person believes as a gospel truth, may not even be IN the Bible.
One person says homeschool only, dresses only, KJVO, natural birth only. They have the "truth" and will separate from other believers over these issues.
Another person says Christian school, NASB, and slacks are fine, but he will not associate with anyone who allows CCM in their church.
Yet another says no shots for their child as it's a "conviction" and they will not fellowship with those who disagree.
Why would it matter if they disagree on such things when they are all born-again Christians striving to love God and live for Him? Again, I ask, what does it matter? Does it matter to God?
