"who is actually educating the younger generation?"

Teachers, peers, media.   Yes, parents play a role. I do think that younger generations do a better job of thinking and using logic than we did.

I happen to live in the same town I grew up in. I had moved out when I got married, and when it came time to move back I did not want to return becaause I remembered the narrow minded thinking that I grew up with in a town that was overwhelmingly white and Catholic.   I was happy to discover that change had occured, and the town is now very diverse. With exposure to so many cultures and religions, I see a tolerance and understanding that my generation could not comprehend.

So, while it will never go away completely, there is reason to hope that it can change and that ignorance is not hereditary.
