Antireligionist or antitheologist? They more specific than antitheist which is opposition to belief in deities, especially intervening and personal ones, and by inference opposition to any doctines or dogma associated with them. And it's stronger than secular, areligious, non-religious, or irreligious. And to the 2nd question: Creation?
Why do we need a word for anti-religion? Who gives a shit if people believe in deism or idolatry? It's the monotheists fucking everything up. Are you seriously opposed to someone who believes in a creator who set the universe in motion and moved on to other things? There are a lot of words for a controlling force in the universe. None of them are omniscient. That nonsense is reserved for religion. Most of us accept that we don't know what we don't know. And that any controlling force in the universe doesn't know what it doesn't know. Like us, it knows everything it knows but it damn sure doesn't know everything. It does know if the world didn't suck we'd all float into space. Maybe gravity is the controlling force in the universe.
When you say: "in control" that sounds like a very religious interpretation of how nature works.
Scientists make claims about how things in the observable universe work. They have lots of wonderful explanations about the universe.
Once Stephen Hawking was asked: "What is outside the observable univers?" Rather than just stating the obvious by saying "the unobservable univers". He dismissed the question as stupid.
And yet it is perfectly conceivable that we just live in a univers that is surrounded by a super univers which is ...etc just like a set of Russian dolls (fuck another Russian connection)
You first question is easy to answer. If you believe in god or gods then you are a theist and if you don’t you are an atheist. The second one is a more nebulous question. My short answer is no, there is no word for anything that doesn’t exist in reality. We don’t believe God controls everything and neither do we believe there is anything else except the laws of physics and man’s interference with these natural laws which could spell the end for us.
I don't believe there is any word yet in English to describe Antireligion other than Antireligion.. which would describe opinion against organised religion.
Maybe intelligent design may go some way to describing a higher power other than any specific God.. but I can't think of another...
I have roughly the same problems with disorganized theism as I do with organized theism, namely, the failed epistemology of religious faith that is deployed to support both. So I see no real reason to make the distinction, personally.
Religion is nothing more than an entrenched, organized, normalized, popularized form of theism. If you believe, without evidence, in an asserted supernatural divine being, then even if you don't conform to a particular group of theists, you are still believing the unsubstantiatable and are still detached from real-world feedback loops.
