I like what Matt Langford writes:
Prejudice exists within all of us, as it is human nature. To separate good from that evil, people must make the conscious decision to fight against that natural leaning and extend a loving hand to all people.
If you are unable to separate the violence by a small few from the peaceful protests by the majority, you are part of the problem. Saying “I am not a racist” does not mean you aren’t propping racism up without realizing it.
