I think you're right, at least if you consider the western society only.

However you should also remember that most of these people also believe that believing what they believe is good, and that not believing it is bad.

So while they don't really believe they have good arguments, they think whoever doesn't believe the same as them is bad. Especially those who don't have another simlar belief instead.

Also, most of these people encourage others to be in the second group, because they think that's the right position to hold, even if they themselves "lack the faith".
