I'm soooooo far outta your league Jocko.
It ain't just Canada, or the US. Empire building has gone on for centuries.
We may feel that our ancestors did unspeakable wrongs, and yes...wrongs were committed. But we didn't do any of these things, and have no reason to beat ourselves up over things that we didn't do.
What we can do is live our lives in such a way that we feel good about ourselves. We can reach out to others who need a hand. Most importantly, we can live in today. Not dwelling on the mistakes of our past, or concerning ourselves about what tomorrow may have in store for us.
Live your best life everyday my friend.
