I make a razor wire distinction when dealing with this particular topic. Faith is a manifestly good thing, Religious adherence is of mixed-virtue, and the "leadership" of religions (that is those "members" outside of your average community worship service) are almost all bad.
Religious leadership has tended toward an incestuous (figuratively speaking not literally) power exchange amongst elites with an eye towards controlling the world. I refuse to take seriously any claims of faith or membership in a religion from people who cannot live up to the basic tenets of their religion.
Religious adherence creates communities, tends to espouse decent morals, and brings a little bit of joy into people's lives. It also tends to foster "follow the herd" mentality, in practice less than savory moral upbringings will occur under religiously dominated upbringings, and in my own personal opinion denies people the chance to figure out what their "true" beliefs are.
But Faith... No, Faith is a good thing. There is a strength and peacefulness attained in Faith and in my experience it doesn't really matter what that Faith regards so long as the Faith is true. Even an Atheist who has found some deep meaningful philosophy on life can have that same "Faithfulness" about them. So in the end I count Faith as being amongst the list of virtuous things that all people should aspire to have (in moderation of course; all things in moderation, including moderation).
