I am a social democrat which is a part of the socialist family as far as I'm concerned. As far as I'm aware, the US-centric framework is what everyone, including socialists, use in the US. Just as socialists else where, such as the UK or EU, use their own meaning for the word liberal.

Based on what you are saying, this particular instance of disagreement does not seem to be a regional one. As regional differences on definitions should translate and be something we both navigate around. What you are describing seems to a disagreement based on definition.

Conflating supporting some form of capitalism, in my case regulated capitalism, ie mixed economy, with neo-liberalism is intellectual dishonesty. You calling me a lib for supporting some form of capitalism is no different than me calling you a tanky for simply being anti-capitalist. Just because you seem to be against capitalism does not make you an authoritarian communist.

Democrats are not currently fascists, so that does matter. I'm registered independent though, so I'm not particularly interested in defending Democrats. If Democrats don't become more progressive, as they are predominately neo-liberals right now, they could easily go the way of the Republican party and become fascist.
