Destruction of language is particularly ugly propaganda because by destroying language you make it hard for humans to even do much rational communication anymore because you've twisted the meanings of so many words around so that now they mean their opposite, or both what they used to mean and their opposite, or else they have been so misused and abused that no one even knows what the word means anymore. So you get a bunch of people talking without really much understanding going on. It's like a room full of people all speaking different language. This is the destruction of communication itself, and that is a grave charge.
