There are two major types of atheism.
There is the negative response to the burden of proof not being met by theists and then there is the active claim that god doesn't exist. Many atheists are the former and not the latter.
I simply reject the claim that god exists because of the fallacious arguments put forward and the lack of evidence. The burden of the theists doesn't seem upheld in my opinion. Thus I'm an atheist. I have a lack of belief in a deity and therefore I live my life in the practical sense like one doesn't exist. It's really that simple.
To be an agnostic does not contradict with this position at all. Hence why many atheists call themselves agnostic atheists and you may even find some agnostic theists, though thats quite rare I should think.
Atheism isn't a religion, stop the strawmans.
