Yes, I agree. I think that's part of the accepting our history and learning from it.
The other day someone was reading part of Langston Hugh's poem Let American Be America Again and this line is so striking:
O, let America be America again—
The land that never has been yet—
And yet must be—the land where every man is free.
I think it really sums us up - We have this idea of what America means, but we've never really achieved it. If we realize that we have hope of someday getting there. Instead, when terrible things happen - like rounding up immigrants or police brutality we all like to say, "that's unAmerican!" ... but it's really not, it's our entire history!
