Well, I will admit that you are drawing it out of me, and I don't really want to say it, but yes, the ability and habit of fooling ourselves is pervasive. Not only for atheists, but for EVERYBODY. That doesn't mean we always are fooling ourselves, except in that we give more credence to our limited worldview than it merits. That is apparently necessary just to keep our heads above water, but one should admit the fact to themselves, just to stay skeptical of their notions. I am not saying it is intentional on the part of any particular person here, in that they realize they are doing it and protect and disguise it, but that it is there all the same. (And like I said, I do it too. I am, for example, more than capable of making a statement I know well is true, and instead of amending it when amending is called for, I scramble to find a way to support and defend it. Strangely enough, sometimes that works out to be a good thing that a person is not too quick to accept apparent evidence to the contrary of what they believe.)
As for Romans 1, by the way, not just my answer to your first paragraph above pretty well answers what I think, but I want to say it is not just about declared Atheists, but anyone who is not made new by God. As a matter of fact, even believers, when they rebel, are pretty much saying/ doing the same thing, claiming their own creator is not real and/or not relevant. My opinion is that their condemnation should be that much worse. "From him to whom much has been given, much will be required."
I've heard of some who became intellectually convinced of the existence of God through that argument, but no, not immediately taking on faith in the logically necessary implications.
As a young teen (I'm 65 now), I knew, and considered it intuitive, (lol, yet it involved considerable reasoning), that God had to be First Cause. I KNEW that to be God, ALL that is, came from him --first on my mind was the principle we refer to as time, then I realized all principle, and indeed all fact, had to proceed from him. God does not fit anywhere. It all fits him. Is that intuition?? Back then, I would probably have said yes. Now, I see that it can actually be developed logically. But, My current level of philosophical clarity doesn't make my faith any more reasoned, nor less emotional, than it was back then.
"It just makes the most sense to me" sounds like reason has occurred. The incapacity to put into words or even cogent thought, or to develop it logically does not automatically indicate fideism. It kind of galls me how Christendom has for so long taught fideism is preferable to reason, almost as if reason is to be avoided.
Frankly I should think we all should understand, as skeptical of self, that reason and emotion are 'traveling partners'. But, when necessary, my emotions defer to reason. The fastest way to describe this, I think, is that old reference we've already been through on this site (maybe this thread --I don't remember): That "FAITH is the evidence of things not seen". (I take that literally. It is not madness. And, btw, the faith referenced there is not merely what is defined in the dictionary, but faith given by God, produced by God. I will describe it more if you wish.)
Yet if I had never heard that verse nor reasoned on the subject, it would not stop my faith from being reasoned. But yes, intellectual assent is not of itself faith. My intellect may fail, but if my faith is produced by God, it cannot fail. Now, that does not make me a fideist. If anyone brings up something to make me question my faith, I don't set my jaw and fold my arms violently against my chest. I look it square in the face.
I think my problem with this is that you seem to want to insist it must be one or the other in the main. I insist both are necessary for intellectually capable people. I also speculate that the intellect involves a lot more than most people realize. Faith is not mostly emotion.
I had not thought of it in terms of 'plains of existence' or better, 'levels of reality' before reading some of CS Lewis' stuff as a young man. And even now, while I consider this life we are stuck in for now as a mere vapor by comparison to what is to come, it is, nevertheless, reality. Christ really died in it, for one thing that I cannot dismiss. (While I like the notion of this being a simulation, I don't think it is. But it may as well be, as to the effect and usefulness of it. It is, I think in some way, after all, quite possibly accurate to say the Omni is all in the mind of God.)
