I think it is wrong to compare one religion with other. All religions are only as good as how much the followers believe in it and so any comparison between them is simpl a comparison between how much 'blind' faith the followers of each are able to rationalize.
Why Islam, even the people at branch davidian claimed theirs is the perfect religion.
Peace Get smart
First of all there is everything to show for in comparing like for like, especially for religion. This is because when one religion is being shown for it's weaknesses then it becomes a moral obligation to provide the alternative so people do not end up without religion rejecting all on account of their own religion being shown to have shortfalls.
Secondly your claim "all religions are only as good as how much the followers believe in it" is again countered by the argument, "do not judge a religion by it's adherents", but more accurately the way a religion promotes itself but at the same time maintains a distance to allow people to choose it is another example of a superior religion. So though it is not THE characteristic of religion it can only be argued that level of adherents are but only ONE indicator of it.
Thirdly, by falsely concluding religion to be just a collection of adherents you then go on to falsely conclude that all adherent are engaged in blind faith. All this needs substantiation. It may have sounded pragmatic to say these things, but substantiation is required.
