Well... Do you?
[spoiler]Ignorance by deffinition is "lacking knowledge or awareness in general; uneducated or unsophisticated" and that is okay. You have just not been exposed to it. It is like saying, I am ignorant at how to fly a Helicopter--and I am ok with that. I have no foreseeable need to fly that thing.
Now Ignant is like this: You are stranded on an island with a helicopter that you dont know how to fly. However, there is a detailed manual there that will have you mastering how to fly within just a few days. You have all the things that you need to get off, but yet you are too damn lazy to do it... That is just plain ignant.
Now if you read this to cheat. Lets hear your own definition.

Ignant is not a word lol, unless the Urban Dictionary is in charge of the English language. But some people will fall for it regardless of this comment >.>
