Not to be a stickler, but definitions are what give us the ability to meaningfully communicate across time and space.

-- ignorance: Lack of education or knowledge. Unaware or uninformed.

Not knowing something makes you ignorant of that thing. Ignorant is NOT A BAD WORD. I use it all the time. I am IGNORANT all the time. It has no negative connotations in its definition. When I say, "I am ignorant on that topic," it means I don't know anything about it, and I say that all the time.

It would be more appropriate to replace the word "Ignorant" with "stupid," "obtuse," or "foolish." I like the last one for this meme. Stupid is too offensive and will prevent an audience from listening, obtuse can be misinterpreted, but no one wants to be foolish.
