Believers!! Don't mislead people

[Esquilax]

So you believe in god or deities (but lack of belief) ?

lack
lak/
noun
noun: lack; plural noun: lacks

1.
the state of being without or not having enough of something.

See? Two uses: either not having a thing, period, or not having enough of a thing. With regards to atheism, we use lack, meaning not having belief at all.

Just because it can mean something else, doesn't mean it does mean something else in every context.
