Y'all, as someone who went down the whole "Christianity is not a religion, it's a reality" schtick (I even used it in my signature here), I really caution you as brothers and sisters in the Lord to not tread the same pathway!
At the end of the day, religion is simply the chosen term for how we, as humans, relate to God. It's used in the Bible for the same purpose. In James 1:26-27, the Bible effectively says religion (aka how you relate to God) is serving others in the name of God while keeping unstained by the world. So, we all have a way of relating to God, like it or not. It's how God built us. There's no way around that. I understand that words like religion and phrases like "organized religion" have all sorts of negative connotations and lack of trendiness, but this whole "hate religion" movement is a pox on the house of Christianity. If you make any claim whatsoever about having anything to do with God, you are practicing religion. I sinned in having this attitude and I repent of it. I urge you the same if you hold it in your hearts.
It's the same with something like an SoF. I'm not sure about you, but when I enter into a place (be it physical or virtual), I expect to know a little about it. I identify Walmart or the local grocery store by the sign on it. I know that if it spells out Walmart in blue letters, then it's a Walmart and will carry certain items. If I walk into a building with Belk on it, I know it's something else and carries a certain range of items.
I do the same with churches. In theory, Christianity should get you to a pretty specific place. In practice, lots of people love to run with their interpretations and call it Christianity after they select a few precious items from the a la carte menu. So, things like SoFs developed to provide a baseline understanding. I want people to get that Christianity Board is a generally traditionally-orthodox community of Christian believers, exclusive of Jehovah's Witnesses and Mormons who are not Christians even though they claim to be. We have to draw that line in the sand. I do not want a new Christian coming on here and falling prey to heresy.
We try to be very generous in what we allow, but 10/10 times I have found that the people who hold to heresy or pet issues that they know run contra to Christianity will not let go of those issues. It becomes a wedge issue and a self-fulfilling prophecy as to why they cannot seem to get along with any Christian forum or member anywhere ever.
The reality is that we have to fence off and define our beliefs. If you say you're against SoFs, then you're simply declaring your own SoF against SoFs. You may call it something else, but by stating a belief against something...well, it's stating a belief.
With respect to the OP, I think a theological system should always be open to review. It's part of the reason I feel a tug between the Calvinist & Reformed camp versus the Arminian & Semi-Pelagian camp or some other topic. I have seen healing via prayer, and that has shifted my thoughts on that a bit. I view this as God semper reformanda'ing (always reforming) me. To me, this is the root of Protestantism to always look at what I am doing and what I believe to ensure that it falls in line with Holy Scripture.
That said, should one be open to the discovery of lack of divinity of Jesus? In theory I suppose you could say yes, but in praxis I find it quite difficult to leave open to doubt. It hearkens back to what the Apostle Paul said in that we really are poor SOBs (okay, maybe paraphrasing there) if Jesus was not risen from the dead (1 Corinthians 15:19). We have nothing to stand on if this is the case. So, I think one can let many issues stand or fall on merit, but I do think there is a core of the faith that should not be open to question, otherwise it's no longer faith. The epistemological considerations would result in tremendous upheavals of thought. I don't fear those things, but at that point it goes beyond just critiquing a system.
