You really have two choices. One, you can work within the system to try to change it by persuading others that your ideas are better. Of course, by doing that, you are implicitly conceding the legitimacy of the laws you oppose by participating in the same process that produced those laws, but arguing that they are wrong or a bad idea or some such. Or, you can refuse to concede their legitimacy, and embark instead on a campaign of civil disobedience and non-compliance with the laws that currently exist. In this case, pragmatic soul that I am, I suggest that the first option is somewhat more likely to succeed than the second.
