Ignorancia

Just wanted to take a moment to vent... why are ignorant people so annoying? Ignorance is having the lack of knowledge, or background/factual information of a particular thing in general. However, the effect in which this person will be proceeding with their "unproven knowledge" imbedded in their mind as if factual information, they, in turn, will plan on using it in the future to make false and incorrect statements based on what they didn't know about the particular thing, or may have heard as a majority of votes for. And being ignorant does not mean stupid. There's a big difference between the two words.
Okay... I'm done!
