Until we can get beyond that within the public school systems, we won't get away from this notion.
I certainly make sure that my children know that there are good, honest, hardworking people of all stripes from throughout history. I make sure they know of their black ancestry, not to mention their ancestors that were elected to office in the post-Civil War timeframe (Shandy Jones was elected to office in - I think - Alabama in the 1870s or so; he's an ancestor of mine).
Do I only tell them of the good things? Nope. They learn both sides of the coin, good and bad. Certainly what I make sure they know is above and beyond what the politically correct teachers tell them at school.
And surprisingly, She-Who-Must-Be-Obeyed and I are among the more popular parents among the teachers at our childrens' schools (well, except for the moronic one when my daughter was in middle school that we called the school board on; scared the living $#!t out of him, too...[g]).
When I read news stories aloud at home, half the time, the teenager looks up and says "That doesn't make sense!"
I smile. She's growing up a fine, conservative that thinks ahead of looking at things emotionally.
