Sadly, the enemy has gotten control over our educational system and the national media. Our students are no longer educated on how to think, but what to think and how to "feel" about it. They have been effectively indoctrinated through lies about history, economics, politics, etc., leaving out important contexts, etc.
Without a truly educated electorate, tyranny is always a strong possibility. The un-/under-educated can be swayed and fooled into voting in some flavor of Marxism which will always lead to tyranny.
Historically, whenever the Communists took over a country, they attacked Christianity in that country, killing the leaders and faithful at will and closing churches. They also confiscated all the guns and weapons so that the people could not fight back. Finally, they purposely destroyed the morals of that country, because an immoral people is always easier to enslave than a moral people.
We see this happening before our very eyes. Many of the young are all on board with Communism and atheism. They haven't been shown the consistent results of that path (over 100 million innocent people murdered) and the misery that accompanies it. Even in our day, we have a great example of what happened in Venezuela, when they embraced Marxism. Venezuela was once the richest country in South America, hands down. Now, they are one of the poorest. Rather than raise the poor out of poverty, they made everyone poor...except the tyrants in charge.
