As a fellow graybeard I strongly agree with you!  Those  awful "righteous censors of history" had control back when I was growing up-- never did we learn about why Oregon was so white, our Exclusion laws, what  happened to the Indians....it was all about "The Winning of the West."  They kept the lid on.

A lot of folks are pretty uncomfortable letting the truth out of the bottle, they'd rather keep our history stuffed back out of sight as it was in the good old days.  Just read the comments here!
