Why is Faith/Belief a Moral Issue?

[orangebox21]

So why should I be interested in US statistics? I'm not American and things look very different in most parts of Europe. I'm aware that the US is about the only Western country where religion still plays as large a role. I'm glad to live in a society where it doesn't.

Because it is "the moral consensus of the particular society I'm living in" and is therefore moral.  If you judge it to be immoral you do so inconsistent with your own standard of morality, namely moral relativism.
