Immoral to oppose immoral laws? Not sure I follow you on that one. However, morality is a community based value system. Morals vary from one group or culture to another. The community (State of Texas) through their elected representatives passed a law that is based on the moral beliefs of the majority of the people in the community. Now, how can you say that is immoral. If a large enough group of people decided that the law was immoral, then they could change the law. Your argument assumes that morality comes from individual decision of what constitutes morals. Under that argument, I as an individual could decide that anything is moral, including murder if I as an individual could justify it.
