I think if nothing else, Obama’s presidency has been worth it to highlight both how far we have come, but even more importantly how far we still have to go to end racism.
I remember when it first became unfashionable to be racist. When people started using code words instead of being blatantly racist. The racism was always just barely under the surface, but it surprised even me at how quickly it came out into the open again. All using code words of course.
