YOUNG VOTERS WANT SPIRITUALITY, BUT NOT NECESSARILY RELIGION. Well, that’s because religion often tells you to do things you don’t want to do, or to refrain from doing things you want to do, while spirituality is usually more . . . flexible.
Obviously, from the context, he means noncommittal, “cafeteria style” spirituality.
Allow me to use a perhaps risqué metaphor: “Young voters want casual ‘hookups’ but not commitment”. Embracing a religion — or deciding to become serious about the one you already belong to — is a lot like committing yourself to one partner and one only. You may be friendly with others — very friendly even — but n the most intimate level you belong to one (or One) only.
