Why don't some people understand lack of belief?

I think it may be because you don't hear much from atheists who merely lack belief, since I assume they tend to be the ones who dont say anything about it. The ones you hear from are the ones who actively disbelieve. So when someone thinks of "atheist" they are more inclined to think of someone who thinks God doesnt exist, rather than just someone who doesnt believe nor disbelieve. Is there someone even like that on this forum?
