you're right to an extent, they are not the same system. But they are rooted in the same philosophy. So called democratic socialism is dangerously close in its language to Marxist philosophy. When is it ok to take an individuals assets for the, "good of the people" or when is it ok to silence a persons beliefs due to it being considered, "dangerous or destructive" to a society. That is where Democratic socialism, and what would result from its implementation, are far to close to the systems of the past.
