I can see that...Ignorance is bliss, but it is also complacency to an elevated degree...more nuetral than anything else, really. A little bit of knowledge leads to false conclusions and assertions. How else did this administration get us into a Iraq if it wasn't for the use of limited information?
A completely ignorant person wouldn't be biased or prejudicial...instead he would be a blank slate waiting to be written on. You could even say that we are surrounded by ignorant people all the time...our children. They are, litteraly, a blank slate waiting to be written on to. I would, however, agree that an ignorant person can be as equally dangerous as one with a little knowledge. It really all depends on whats written onto the blank slate first, though.
Teach someone that black people are bad and his ignorance is elevated to the realm of dangerous.
