You don’t need to. I don’t think that’s the point of this thread, if I’m reading the OPs intentions right.
I agree with the previous post by
@Magicpole
You don’t need to feel ashamed by an objective look at the story of how you arrived where you are today.
Every country has shameful deeds in their history. Over here in Ireland I would immediately think of the Magdalene Laundries and Clerical abuse hidden by the state and the church, which had far too much power.
The point is, do you acknowledge this, address it and learn or grow from it, or do you just say that’s got nothing to do with me?
Your point about the Crusades…
Do you think about them much?
I shouldn’t think so. But…..
Religious wars dominated Europe over a millennium and how they affected various countries through the ages is part of the story of where we are now. That’s just a fact.
Not everyone is interested in history, they’re too busy living life the best they can.
I personally think a healthy respect and objective knowledge of history would create a far more tolerant attitude from people towards others who they deem as ‘not us’.
