"[T]he conservatives of all ages are thoroughly dishonest"

Whenever I read the tortured "philosophical" defenses of traditional marriage and attacks on gay marriage, I am always reminded of this remark of Nietzsche's:

[T]he reasons and purposes for habits are always lies that are added only after some people begin to attack these habits and to ask for reasons and purposes.  At this point the conservatives of all ages are thoroughly dishonest:  they add lies.  (The Gay Science, sec. 29)
