At least, that's the lesson I learned from listening to the MANY immigrants of the 50s through 90s that had experienced Leftist government eager to squash them into conformity. Frankly, the Leftists in academia seem dedicated to reducing their students to soulless automatons of Leftism. One of the most powerful mechanisms for encouraging and promoting Freedom of Thought is the public library. Unfortunately, librarians have become radicalized from those sweet old ladies we remember from our own younger days. They no longer work to open the minds of the borrowers; their new mission is to shut down thought. Their method for accomplishing that? Get rid of the books. They don't have to do a Fahrenheit 451-type burning - instead, they just cull "old books" - those books that don't have the Correct Thinking on the New World Order. No flames, just a book sale. With the unsold books going to recycling. No nasty photos reminiscent of the 1930s Nazi book burnings....
