That’s like saying oranges are basically apples. They aren’t even claiming to strive for communism. Unlike democratic socialists who want to achieve a state of communism, social democracy is the end goal. The end goal is to have the government clean up where capitalism fails, but still keep capitalism and private property around. You could make the argument that all socialists are communists, but social democrats fundamentally aren’t. It shows that you have no idea what communism is. Communism is not “government does stuff.” It’s an unrealized political ideal that is not about the state dominating everything. In fact, plenty of communists are anti-state.
