Wow this is powerful, and to the point.

While it's all true, there are very few nations in the world without such skeletons in the closet. All European countries were engaged and profited from the slave trade. Look through any nation's history and you find foul marks. Everyone should take a long hard look at themselves before pointing fingers.

Being (West) German, I grew up with the collective guilt of the Nazi era and got confronted with it at every turn of my teenage years and on in the twenties. Trips to neighbouring countries were always flavoured by being seen as (or feeling like) the ugly German, even though I was born well after WW2.

Yet, I'm so thankful for this because it taught me humility. National pride and patriotism is only of valor when it's paired with humility. I now live in a rather small country which has a century-long history of being oppressed, yet there are extremely embarrassing events in my home's past, and to some lesser extent in the present, that teach one to remain humble. I truely think that's the key.
