Is it wrong to be proud of your ancestors?
Are men like Jefferson Davis, Robert E Lee, Stonewall Jackson to be "vilified" like Hitler; to the point where their names are being eradicated from schools, roads etc.?
I think it depends on what you are proud of your ancestors for.
Fighting bravely, defending their homeland- of course.
Owning slaves- not so much.
I have an ancestor who is known for having killed the last kind of a specific species in one state- I am proud of him for many other things(he did fight in the Civil War)- but not for the localized extinction of a species.
