I'm sorry to butt in again (actually, no I'm not sorry at all) but...equating atheism with non-theism IS false. And that IS one of the problems you will face if you go with the "majority opinion" - especially on RF - and even more especially if its a "majority opinion" about the definition - or rather label - of someone else's beliefs.
For the record, etymologically, atheism is not opposed to theism - the word is better understood as athe-ism rather than a-theism...it is "without gods" not "without theism" - in other words it is opposed (etymologically) to belief in any deity - not just theistic deities. There are non-theistic ways of believing in deities - deism is an example, as is naturalistic or scientific pantheism. These are not theistic beliefs, but they are not atheism either.
Anyway, coming back to the idea of basing your understanding on the "majority opinion", I would ask you, do you suppose that Jesus, or Buddha did that? What do you suppose Jesus meant when he talked about the "narrow road" that "only a few" would find? (Matthew 7:14). Do you suppose that God intended us to base our understanding on public opinion? Or do you rather think that he intended us to use our intellectual capacities to figure things out for ourselves?
I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use. ~ Galileo Galilei
