I know for a lot of people a tankie is just something that they know it when they see it, however I think that it is important to think about the reason that you define something as being tankie vs just a leftist.
What “ideas” are you here to challenge? This is a libertarian socialist community that is against tankies, if you don’t fit that criteria then this isn’t a good place for you.
I like libertarian socialists, I might be one myself. I just think that the word tankie gets thrown around a lot. If everyone (I don’t like) is a tankie, no one is.
Let me put it this way; If Bernie is a sexist (and he was called sexist many times from different groups of people), then everyone can be called a sexist, and the word has lost it’s meaning.
