Is that why the Regressives are out to destroy the meanings of all words?
Yes. Godwin's law* on steroids. "Socialism!" is the new "Nazism". The goal of regressives is
to shut down all rational discussions, because rationality is the enemy of regressionism. They co-opt all kinds of language and corrupt their meaning like a Russian malware attack. "Conservative", "liberal", "socialist" are all subjects of their attacks. By destroying the meaning of words, it's like a DDOS attack that renders discussion impossible.
All the friction between left and right is just about the details about which things should be government-controlled. Only the Communist Party and the Extreme Libertarians favor all or none, when it comes to government control, and everybody knows they are insane.
We've already established what you are, now we're just dickering over the price. It is easy to disrupt any discussion by painting your "opponent" with extreme branding. It goes on here, as well (e.g., painting Obama and Clinton as corporate shills). Moreover, by muddying the waters, extremists get a pass when they really are
doing the bad things we fear. That is one thing that Trump has done really well.
*Godwin's law (or Godwin's rule of Hitler analogies) is an internet adage asserting that "As an online discussion grows longer, the probability of a comparison involving Hitler approaches 1"; that is, if an online discussion (regardless of topic or scope) goes on long enough, sooner or later someone will compare someone or something to Adolf Hitler or his deeds. (From Wikipedia) I heard a great discussion on NPR including Godwin, himself, about how extreme language choices shut down rational discussion. Wish I could link it.
