Don't pretend to know what Liberal means in the states, but over here in England Liberal is a good thing, or at least it is to me. Currently we have a Government who feels that servicing the people who already make STUPID MONEY at year is a better plan of action than dealing with things like Immigrations, Unemployment, the state of the NHS and all that jazz.
So the idea of a Liberal Activist Superman doesn't exactly sound BAD really does it? Doing something about the state of people for the people isn't a communist idea so much as a humanist idea. For some reason being nice to people and trying to provide a baseline existence for humanity is labelled as Socialism or Communism instead of being humanism. Providing basic things like not getting shot in the face, and being able to feed your children isn't a bad thing so I don't understand why giving Superman a Liberal activist stance is going to cause the uproar I can already see on Bleedingcool. This is like Superman giving up citizenship for America - When your identity is fluid, and based on your personality, nationality doesn't even play a role, it's simple a place where you are born.
Anyway, tiny rant there
