Thomas Sowell is one of the clearest thinkers and writers I have ever read. He always gets to the point, and clears the muddied waters. It must be generational, he puts younger columnists to shame by never getting sidetracked.
Sadly, Sowell fails to call the enemy by name.
Our American enemies are Marxists. They aren't "left", "liberal", "progressive", or "socialist. To call them anything other than Marxist or communist is not clear thinking.
Marxism is our nation's **most** serious threat! Schools are the Marxists most important weapon. That Sowell fails to call for their complete closure, and fails to warn parents to remove their children immediately from government K-12 schools is also a failure of clear thinking.
