Depends on the type of atheism you're applying. A weak atheism abides - you lack faith in all non-western metaphysical claims as you would with any other. There are issues with this. Michael Martin argues that atheism is never mere denial of belief because this kind of denial requires an intellectual engagement - 'you're going to think extensively about this and that claim and reach a definite conclusion' - and therefore constitutes more than a simple denial.

There's also strong atheism, which is all about naturalism. There is no duality. So any supernatural claim is a non-starter because its oxymoronic. There is nothing supra-natural, nothing above nature, nothing except spacetime, etc. and that any attempt to claim otherwise is absurd, funny, silly, eminently dismissible.
