If you don't know what you're writing about, shut up

This from Kotaku about Senator Brownback, soon to be former Presidential candidate:

Introduced in 2004, the Nintendo DS (for Dual Screen or Devil Screen), this game machine has sold some 700 million or so units. That's an epidemic. It's undeniable that it has been a "success" for its Japanese manufacturer, Nintendo (makers of Donkey Kong aka Monkey Donkey, a game in which a monkey kidnaps a young girl to satisfy his bestial desires). It's also been a tremendous success for pedophiles everywhere.

When I was a kid, my dad sneezed, and I replied "Gesundheit".

"Why did you say that?" my father asked.

"It's what you say when someone sneezes," I replied.

"What does it mean?"

I thought. "Bless you?" I knew that's what you said when people sneezed as well.

"If you don't know what something means, don't say it."

I later learned that Gesundheit means "Good health", and that's why it's a nice thing to say when people sneeze. Brownback, and others like him, might take the same lesson:

If you don't know what something is, don't talk about it.
