My Definiton of Being Foolish and Ignorant

Now, those who have read my Pivot Questionnaire know that I despise ignorance. I mean, I spit upon it, I would rip it apart if it was dimensionally possible. I just hate it. But let's be literal here for a moment and look to see what Webster has to say about these:

Foolish(iness): resulting from or showing a lack of sense; ill-considered; unwise: a foolish action, a foolish speech.

Ignorant(ance): the state or fact of being ignorant; lack of knowledge, learning, information

I agree with these meanings, it exactly how I feel about these. It's just that people who can be foolish can be ignorant at the same time. Or, even better, they are so foolish that it would be foolish NOT to call them ignorant. I mean, it burns me to see people who know that they are doing wrong, but they continue to do it. And they justify that they are right!

Foolishness is something that you can get away with.
People laugh, a cute little joke, nothing serious.
It can be taken lightheartedly, a foolish person is not dumb.
As long as you know it was playful; that it the rule of thumb.

But ignorance is an undertaking on a whole new level.
Something that turns me red; red as the devil.
Must we be swarmed with the painful setbacks?
They are being irrational, can't they see that?

Foolishness is manageable; it can be controlled.
Why can't ignorance be? That's what I want to know.
Foolishness versus ignorance; there is a clear difference.
There are other explanations, another inference.
So let's not destroy the world with senseless ramblings and unconsidered thoughts.
Foolishness and ignorance are two different things, that's what I'm talking about.
