Of course racism still exists. It always will. However in the US racism is nothing close to true racism in other parts of the world.
The US is the antidote to racism. The problem here now is that racism is a for profit industry. Many people depend on it in order to maintain their lucrative living, so they ensure their roil it up whenever possible. They get away with finding racism in anything. Even a well maintained lawn in your yard.
Claiming that racism causes the earth’s climate to be cyclical is idiocy of the highest degree.
