Atheism is what it is.
And what it isn't? Everything is what it is. I take your comment to mean that atheism is a colloquialism of sociopolitical and philosophical dispute?
A term generally used to define the non-adherence to popular deistic/theistic ideologies.
Ideologies specific to those, you mean. Theism doesn't adhere to any general ideology at all though, does it? If anything, and anyone can be a god or gods then to be with one doesn't require any specific ideology unless you consider the general adherence itself the ideology. Singular. One can believe in God, reject God, even have faith in God and still be atheist because one doesn't adhere to that God. That is, doesn't venerate/worship God. Atheism simply means without God or - and this is very important - or gods. The problem with that is that anything or anyone can be a god. Money, food, sex, love, sticks, stones, bones and words.
The only commonality necessary between any of the myriads of gods is their being worshipped.
Though as ever, if one deconstructs the idea and expands upon definition, then the loose adherence to any social idea could be regarded as being theistic.
That seems a contradiction to your opening statement, which I expected and so replied with "and what it isn't?" If one makes the argument that atheism is simply a constructed idea defined as "disbelief in the existence of God or gods," that is nonsensical for a variety of reasons. First of all, it begs the question what is a god and why the distinction between God and gods, i.e. which God and which gods? Second, what is belief? Trust or acceptance? I believe our government exists but I don't believe in our governments, for example. Thirdly, as mentioned above one can believe and even trust in a God and still be atheist if they don't venerate said God. I'm apolitical. That doesn't mean "disbelief in the existence of King or kings," it means I'm without politics.
So, in terms of the Biblical magician [...]
Which I'm guessing you know virtually nothing about. Maybe you think he is alleged to have created the universe is 144 hours, sends people to hell, is three parts of a singular, came to earth and was hung on a cross, et cetera?
[...] I am atheistic.
It doesn't make sense to me that you are atheistic in terms of one specific god and theistic towards others. I don't believe (trust in or accept the literal existence of) the mythological Zeus (Roman rulers were also given the title Zeus) but that doesn't make me theistic in terms of the Biblical Jehovah and atheistic in terms of Zeus. Zeus and Jehovah are both gods whether or not they literally exist or I personally worship or believe in them or not.
But in terms of a GOD principle, I am open minded.
It doesn't matter, you know. If the Biblical magician as you call it, exists, he doesn't reward those giving him the benefit of the doubt. For merely being open minded. If, by GOD principle you mean a reflection of the specific magician without the responsibility it's a dawdle. If, however, you mean you are open and tolerant to interpretation it remains in a narrow window ideologically, I would think, being simply limited by definition. You only have to venerate something or someone. The Biblical gods, like any others. So, the so-called GOD principle isn't based upon the Biblical or any other. The Biblical and all others are based upon the principle.
Put simply atheism and deism tend to model their perception upon a paradigm that is, and as we've established, isn't.
Is that grammatically correct? I am open minded to the GRAMMAR principle.
It all depends upon how one arranges words.
A lone man makes his way slowly across the alluvial plain. He's cold, wet and hungry and there are piercing eyes glowing in the dark - following him. There's no wood to burn but eventually he stumbles on a dried clump of bovine excrement. Bull shit. He notices there is an abundance about the place and begins lifting them, supping on the creepy things crawling underneath. He then lights them afire. The fire warms him, protects him from the onslaught of savage beasts so that perhaps he may even roast them.
You know what I'm saying? The dung becomes his God. Think - fertility. The fertile land. Crops, children, procreation. Fucked. By the shit. We - are the flowers that grow from the shit. Unsure if we are dreaming that we are a butterfly or a butterfly dreaming we are - we. Huh? Gods are what we make them.
I couldn't resist going all wonky. Sabotaging preemptively.
