There are many today tearing down the country we have. These people are often in very influential positions such as "liberated" college professors. They are often infecting the lesser educated.
Most of them do not recognize that the only reason they have an environment for "free speech" is the sacrifice of earlier generations who loved this country's freedom environment enough to sacrifice their lives to keep it this freedom way.
Those deceased would not understand those "brave" professors, etc, who wish to tear us down. The country is not perfect. Nothing human will ever be perfect. But is the best system created so far in all of human history.
I'd like to see these professors, et al, visit the countries they are advocating and while there try speaking out against them. Jail and death would be the result. Maybe then they would appreciate what they had.
