What do you do when people are so ignorant they don't even know that they are ignorant?
The answer is get out of the way and stay there.
Sadly It is not safe to educate the un-willing nor is it safe to educate the willing, but we have to try, don't you think? The good news is the experience will help me personally get rid of more of my own ignorance. Funny how the ignorant turn out to be the best teachers. LOL
Well all you can do is speak, and those who don't want to hear don't. Talk to those who want to receive ;) Those who are unwilling don't want it indeed.
