I believe we all need to laugh at the past as well as learn from it. Human is human. 21st century come on people!
We should always find laughter in the worst of things not to numb the subject matter but to take away the power of hate that fuels it. The day we stop thinking about racism is the day it stops. By even talking, thinking and even considering there is a difference in itself is racism. We are one in the same. The day it isn't even considered is the day we have moved forward.
