I'm curious what form of math you are using where 34% = 80%?
I am curious why you cannot understand what I have stated from the outset which is the inverse of what you just cut & pasted;
Then the onus is on you to establish that M-W is wrong.
In the absence of evidence the only position which is not belief is one of total neutrality. Are you totally neutral on the question of the existence of God? Do you hold that the position there is a God and the position there is no God are equally valid?
My personal position is not germane to this topic. However I have no problem stating my personal position and I would appreciate you reciprocating.
I am a spiritual atheist. By that I accept what is factual and provable over what is religious dogma and belief. There is no factual evidence for the existence of an omnipotent creator. Furthermore omnipotence is a logical paradox. That does not exclude the possibility that there aren't beings in the universe with "godlike powers" but that doesn't mean that they are actually gods. Today we can strike down someone with a bolt from the sky on the opposite side of the earth. To anyone living 200 years ago that would appear be a "godlike power". There is evidence for spirituality and it has been found in other mammalian species besides ourselves. There is zero evidence that spirituality has anything to do with the existence of any deities. It is merely a trance state that we can achieve through prayer or meditation.
Given all of the above I uphold the right of others to believe that there is a God since to do otherwise would be to limit my own right to freedom from religion. They are both equally valid under the same Constitutional right. Neither position supercedes the other.
The definition you provided refers to belief, and then you say belief is irrelevant. I am not following that. Belief, unlike religion, is entirely personal. So the only thing which is germane is personal belief.
My position on Atheism is that is it a belief like any other belief based upon my own discussions with people who say they are Atheists. So I find the definition of Atheism as a lack of such beliefs to be false on its face.
What you are talking about is legal rights. Which has nothing at all to do with the definition you provided.
To your numbers, you seem to be counting people who do not believe in the typical western concept of God with people who call themselves agnostics and atheists. If they thought there were included in that number, they would have placed themselves there. I see no reason to accept your authority to do it for them. The actual numbers from your site is 13% atheist, 30 agnostic. Anything beyond that is fudging the stats.
I have no problem sharing my own beliefs. I am a Buddhist. I do not believe in a Christian style God. So you will understand if I don't appreciate your shoving me into a box marked "Atheist" so you can jump up your numbers.
