There is no doubt that racism still exists. We've all seen it, both in soft and harsh versions. The important thing is, where do we go from here?
As you state, the left uses racism to contain people - almost like how a dog owner uses an invisible fence. What is interesting in the case of the leftists, is that the fence doesn't exist...Republican won't burn minorities at the stake if minorities cross that fence.
The key, is to show everyone that the fence is fake.
I think a “caste system” also compares.
