If I were blindly standing behind something I did not know first hand and/or study, then, yes, you would be correct--that would be dangerous.

Since I come from a point of study and personal experience, then, no, it's not close minded. I've considered what you posted many years ago when it was presented to me by others. To me, history is not, revisionist as it may be for most, something one can wholly divorce oneself from. Especially history that is still impacting our societies, today.

Your statement is telling to me in that I sense you need to win an argument after I've noted we won't agree that history of slavery or stolen land is not your responsibility and in my opinion, it is everyone's. We simply don't agree and life will still go on.
