All you need to counter this kind of thing is recognize a proper counter argument. No matter how many times a person looks at a dog and tries to convince me that it is a cat it will never work. I have information that says otherwise as well as common sense.

The argument that you are posing is very similar to the old debate that says people who watch too many violent movies become desensitized to using violence in real life.

It's proven to not be the case. If anything, free speech is the most important tool for preventing mind control propaganda tactics.
