Absolutely.
I have always found that when you single out certain segments of the population to celebrate its' differences, that it is affront to unity among the population. How can we be one American people when we say "You are black, you are different" or "you are Hispanic, you are different"? That leads to people wanting to truly be different and thoughts of exclusion. No matter what anyone's past is we are all American. Yeah, America has had a rough and sometimes dark history, I get it. No one alive today we there for slavery. You may have had some old timers around for segregation. But point to me one ethnic group that has not been oppressed in history?
When my Roma (Gypsy) grandmother came to the United States in the 1930s, despite many generations of treatment that would make the Jim Crow Laws look weak, all they wanted to do was assimilate. There was no, I am Roma, look at me, you don't understand me. It was, let's be members of our communities we live in, let's be American.
Just my thoughts.
