They were a long time ago about when my ancestors had the same thing happen to them when they were driven out of Ireland
Not exactly the same. The Irish were persecuted largely for religious reasons.
Not just whom they were, IIRC. Moreover, they didn't have a sovereign government,
who made solemn treaties which were then broken. Still, there are similarities. Ethnic
cleansing and all. And, it just wasn't considered a big deal then.
