Since when did religious affiliation have anything to do with love?

Do people honestly do not know what love is?? Sure you can have preferences, like tall / brunette / doctor / 6 pack, but love defies. Love hits you when you least expect, and sometimes you'll find it in someone you never thought. It is illogical and has no boundaries or rules. So do these people who have this little check-list not know what it is like to fall in love?
