and progressive means to always advance. Should all things always advance? Certainly some should, but probably some should not. I can think of several historial figures that technically "progressive" in their agenda, although I doubt you would approve of it.
Words in politics don't really mean much anyways. For instance while I was in college the muslim student association and the israli student association HATED each other. One group hosted a speaker, and the other group protested to the university that it would disturb the "excellent relations" between the two groups. This was BS, everyone knew that particular group just didn't want that person to come and it had nothign to do with "excellent relations," - they hated each other. But, it got the event cancleled. Good example of telling a lie that it is hard to be called out on - use positive spin to cover up real agenda.
