It’s relevant because if we go by your logic, then the entire country of USA is made by and for cowards since all of them, except for the native Americans, are either immigrants or descendants of immigrants. Ergo, the United States is inherently cowardly.
I don’t think that. I’m just applying your logic to the reality of the United States being a nation of immigrants who aren’t native to the land they inhabit. Therefore it is a nation built by cowards. People still migrate to the US today, btw. And they marry the descendants of the cowards so the cowardly traits will never die out there.
Or maybe, just maybe, people who migrate to another country are just looking for ways to live a free and happy life? Maybe those to move some place else have better opportunities somewhere else and they prefer to live in peace with their family rather than being potentially thrown in concentration camps or killed by their government. It is so easy to sit there and say that people who move away from an area are cowards. Just like it is easy for me to make the conclusion that all of US is cowardly because all of them (except the natives) either migrated there or descend from generation upon generation of migrants. You are correct in objecting to that conclusion and calling it strange because that is indeed a strange thing to conclude. Just like it is strange of you to conclude that those who move away from the US currently are cowards. It is strange and a downright foolish statement to make.
