Why do you appear to lump English speaking blacks who have been here since the 1600s with the Spanish-speaking Mexicans who are just arriving here. Historically, the slaves and descendants of slaves are as much American as any of us.
You're out for an argument and I'm not going to bite.
Read what I said. Diversity doesn't include most anything that is American. That's why there's now a move on to get rid of Old Glory, George Washington, Thomas Jefferson and a sundry other American Icons.
Starting with the Confederate Battle Standard was just the easiest way to set a precendence.
