You're still flogging the argumentum ad populum fallacy. Truth isn't determined by how many people believe it but by if it is actually, factually true.
Well, I know that you know that this is fallacious. I have not made a single statement about my religion, I have asked questions about his logical conclusion, that turns out to be far from logical, in order to compare his lame psuedo purple dragon to the entire rational and logical Plan of Redemption. As in "How many people follow your belief?" They are question intended to get a better understanding of his logical conclusion and not mine.
How many people fell for that "The Secret" hokum that Oprah was flogging? Does it make it any more or less true based on who bought the stupid book?
Personally I prefer the case of cigarette smokers. One could claim that smoking is a healthy pastime, since millions of people do it. However, knowing the dangers of smoking, we instead say that smoking
is not a healthy pastime
despite the fact that millions do it. I know nothing about Oprah's book. I am also not smoking cigarettes. I am eating healthy fruit for the soul, so, argumentum ad populum does not apply here as Christianity is not bad for your health, on the contrary, it produces well round morally accountable individuals who are an asset to our communities and society.
In this case it is considered to be a majority rule or a general consensus. To say that 2.2 billion Christians cannot all be wrong is an accurate statement to make as it could be equally true or false, there is no set answer. It is, therefore, not an appeal to numbers but it is evidence that there could be validity in the belief, or not. The validity is only valid to the believer but the false conclusion is only relevant to the atheists. There are 1.1 billion non - believers in our world. So twice as many people believe christianity is right then think it is false. With no absolute definitive answer numbers are an important factor as we know that the answer could be either true or false.
Incidentally, there are approximately 7.4 billion human beings on this planet. 2.2 are Christians, 1.1 are atheists and 4.1 billion believe in other supernatural metaphysical entities. That equates to 15% being non-believers and 85% believing in something.
