Yes, if people could only remove the if's like racism, then we could get to the core of what are causing the problems poor education results, violence, drug trade, out of wedlock children, unemployment, etc. While 'if' is only a two letter word, it is a huge concept.
...I could not have said it better myself ...thank you ...my man!! 
Prior to the Hitler, Germany was one of the best places for jews to live relative to discrimination. But just one crazy nationalist movement lead by an evil man was enough to result in the worst atrocities of the 20th century.
I’m on the opposite end your situation and our experience’s differ. I am white with a black wife for 22 years now. The only racism I have experienced was from group of black guys in the mall. They could not contain their jealousy that I had a beautiful woman and they did not. I never taught my biracial children that they should worry because they are mixed, or that whites are going to create a disadvantage for them.
I tend not to be as harsh as you, but you know I can not offer an effective argument against the harshness. Perhaps I am a dreamer and I have certainly seen some unpleasant things.
Look at the facts and be the judge.
The majority do get blamed for what fringe elements do. People need to be watchful of those they are associated with.
