Satan's greatest weapon is the lie because after all, he is the father of all of them.
One of the greatest of lies is to change the meanings of words, so that they become the complete opposite of what they used to mean. This is designed to create confusion and allows liars and slanderers to brainwash other people with their inverted moral values. Of course the Bible tells us that people who engage in such practise are not favoured by God.
Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!
I'll give you some examples.
The political terms Left-Wing and Right-Wing were named after seating arrangements in Parliament during the French Revolution. The people who sat on the left wanted more government involvement to help with social issues, the people who sat on the right wanted less. So the terms Left-Wing and Right-Wing were coined to mean supporters of large-government and small-government respectively. By these definitions Marxism, Fascism and Nazism are all Left-Wing whereas Libertarianism would be Right-Wing. Extreme Left-Wing is tyranny. Extreme Right-Wing (no government at all) verges on Anarchy.
During the 1920s and the 1930s the newspapers frequently referred to Adolf Hitler as Left-Wing (which he was) but the Communists who did not want to be associated with the Nazis eventually persuaded the Media to refer to the Nazis as Right-Wing by pointing out that their politics of equality was the polar opposite of Hitler's supremacist ideology.
Thus over time the meaning of the terms Left-Wing and Right-Wing have been changed to suit a political agenda.
Since then we have seen politicians and politically driven academics attempt to interfere with things by changing the definitions of words to mean their exact opposite or to distort the meaning sufficiently to cause confusion. By the same process we have often seen words being hijacked or banned altogether.
It's the same methods used by those who call themselves 'Politically Correct'.
The word 'gay' which originally meant carefree and happy has been hijacked by the homosexual lobby in order to add a positive spin to the disorder. The hijacking has been successful. In the same way the word 'Liberal' which at one time meant tolerant and carefree ( a Libertarian trait if anything) has been hijacked by the Political Left to dupe people into thinking that they believe in freedom - but today's Liberal is often an intolerant believer in large government and wants to control everybody elses lives.
George Orwell warned us about all of this.
Freedom is Slavery
Truth is Lies.
This is how propagandists work. They are unable to solve problems in the real World so they redefine them. They seem to think that a problem is no longer a problem if you no longer call it a problem but call it something else instead!
So we can see how this is happening in the World today. What's more it is getting worse. One of the biggest lies is that the World's most violent, oppressive and warmongering religion is allowed to label itself as the Religion of Peace. This is Satan at work. Notice too that most of the con men who engage in such practises are either Atheists or worshippers of false gods.
Don't fall for the lie, don't fall for the spin. Always believe the evidence of your eyes and your ears and not the words of liars and deceivers.
Her are some more things that have changed.
Abortion (murder) = Womens' rights.
Defending yourself against attackers = Aggression (Israel knows all about this).
Sexual deviancy = Normal and natural variation.
There are more examples. I'm sure that you are aware of them.
