Again, its important to understand Romans 13 in the context of all that God has revealed to us in the bible. Clearly there are times when christians are called to obey earthly authority, but there are also very clear mandates for christians to stand up demand a just society that reflects God's concerns for humankind. Ever since Peter and the apostles were brought before the Sanhedrin, and the prophets to kings and queens before them, christians have being say to the poweres that be that "We must obey God rather than men!". Paul did it (and was executed) , the early church did it (and were persecuted), Methodists in the first trade unions did it (the quote in my sig. is from one such person who was sent to Australia as a convict for it), Jesuits in South America did it (several were martyred), Martin Luther King Jr did it (and was imprisioned, defamed and shot ).
