@snood,
The quote was really rather tongue-in-cheek, didn't you get that?
However...
Often people who are in love (or love their families) are thought of as "crazy" -- but seldom by themselves. Mostly by others who don't have their strength of faith in the family (family values, bonds between members, etc.). This goes for almost any belief system
People who are "with you" in your faith (of whatever) also believe in you and help to fortify that belief system.
People "on the outside" of that faith system often think you are "crazy".
So, it depends on your point of view (whether you are on the inside or the outside)...
