Calling your opponent a racist or clinging to the belief that racism is still a big problem in the US is an act of supreme laziness.
Everyone wants the world to be better. As C. S. Lewis said, there is no such thing as pure evil. Evil is just good distorted*. When they yell, "Racist!" they are trying to improve things by bringing attention to your supposed anti-whatever biases. As an added bonus, if they're right, they don't have to do anything else.
Racism is a big, broad, societal problem and it's solved by awareness-raising marches, finger-pointing and yelling. Once everyone knows that racism is the problem, we can get down to solving the issue and confronting our deep-seated bigotries. The lefty's job stops with pointing and yelling.
If the problem is behavioral, however, the job is demoralizingly enormous. If the problem is the obliteration of the traditional, married family and the lack of fathers, then each individual, affected person is going to need someone to fill that role and supply what's missing. There's no government program or collective community organizing that's going to take the place of the paternal guidance. You are going to have to do it. You, personally and you'd better plan on spending a lot of time with a single person and with a low chance of success.
That's not as much fun as marching and chanting, is it?
A flash mob robbery in Chicago. These young men have had 14-18 years of cultural barbarism leading to this. If the problem is behavioral, you're going to have to do the hard work of replacing that life-long imprint with a civilized one.
Pick one kid out of the pack in that video above and try to figure out how you would make a difference in his life. Chanting and finger-pointing on the Internet isn't going to do the trick. You're going to have to get involved. If it's behavioral, you're going to have to give up things you love doing to struggle to overcome years and years of barbarism.
By the way, there are millions and millions of kids like the ones in the video.
Nahhhh. It's racism.
* - Or something like that.
