You won't get very far by using that term. Just like yelling, "Hitler!" every time someone says something you don't like, it only sounds like you're trying to shut down further conversation.It's used heavily by people on the right as well. The right has placed fascist and socialist in the same pot, which to anyone with an ounce of knowledge of history makes no sense. The right loves calling us commies (another term which has been way overused) and Nazis.
I'm not trying to use it as an insult. I'm trying to make sure we realize what is going on and how we can fix it.
