“Atheism is not being convinced a god exists. That's not a knowledge claim. I don't claim to know a god does or doesn't exist.”
A negative claim in the affirmative is still a knowledge claim. This was settled in philosophy years ago. Now, if you're going to claim you don't know if God exists – you're not in fact an atheist, but an agnostic.
“No, atheists don't all have the same worldview. “
They in fact do. Whether they self identify with that world view is an entirely separate issue from their rejection of God implying it. Now, if you're going to attempt to bring up nuances in atheist positions that would counter argue that position – you had better make sure they're systemic in nature.
“Atheism is a position on one issue only: the existence of a god. “
With direct implications on several others. Denial of this makes it no less true.
“The atheists I know don't believe in any supernatural causes for things, though. And natural causes is not the same as "random occurrences". You're making another straw man. “
Ok, go ahead and tell me then. What force is guiding the universe. And if you're going to say none. How is that not random?
“Atheism is a position on one issue only: the existence of a god. “
With implications regarding several others. Repeated denial of this makes it no less true.
“Things being self-aware is an entirely separate issue.”
No, it's not. It's directly relevant to the topic of God and evolution. Our being self aware is what distinguishes men created in God's image from animals.
“Another straw man fallacy. Atheism isn't a worldview “
It's not a strawman fallacy and Atheism is in fact a view of the world. God alone accounts for truth, reality, morality, and the epistemic means by which they're known. When you reject God, you reject an objective basis and epistemological source to determine these categories of knowledge.
“and the worldview of atheists doesn't necessarily say things arise from chaos.”
It doesn't have to say it – it directly implies it by virtue of it's rejection of God. This is one of many argument from silence fallacies you've committed.
“Even if you say I did, that doesn't change the fact that you made numerous strawman fallacies “
It's not a fact until you have counter argued the points. Denial as a counter argument or perspective is no counter argument or perspective at all. You simply slapping the term “ strawmn fallacies” is an attempt to throw up your hands and declare victory.
