Yes, Biblical inerrancy is a big one and one that nearly every mainstream Christian church teaches. Those that believe the Bible to be wrong in several places are defintely the minority.
And what you say is the very reason why I personally don't attend a denominational church. There tends to be a more strict statement as to what you can and can't believe. But I haven't found this to be the case in the churches that I've attended. In fact on a few occasions I've gone to the pastor following a sermon, and told him what I disagreed with. We were able to discuss the matter and while we still disagreed at the end...it was ok. No df'ing because I didn't believe what he taught.
That's not going to be the case in every church. And I'm not trying to give some false impression of unity, as JWs do. As you said, youtube is full of religious people bickering and condemning each other. I'm certainly not attracted to that.
Some churches are mainly social. But I'm not attracted to those either. There is a growing movement to encourage more intellectual study in churches today. And that is what I'm personally hoping for. Give the Christians some backbone.
