I would disagree. Since Obama was elected they are as bad as I have ever seen them.
The fact that Obama even got elected AND could possibly win a second term, shows that race relations have gotten better.
The days of the KKK and the Black Panthers drawing large number of youths are gone. Sure, both groups are still there, but these types of militant organizations, being part of mainstream America, are a thing of the past.
And more and more minorities, not just blacks, are filling in positions of power in this country. And it is a good thing. One of the justices on the supreme court is Latin American. And a woman at that.
