Rights are what you assert for yourself. You can, of course, assert that you have dominion over others, but you'll have to persuade those others to agree with your if you hope to exercise that, which is unlikely but not impossible - churches are full of people who want to be relieved of the burden of freedom qua moral decision-making, and are thus fertile recruiting grounds.
Of course you may also assert rights but find them denied by law for one reason or another. In which case you can choose to give up your rights or fight for them at risk to your person. Laws are merely the product of political process, which may or may not be corrupt. If you feel a law is unjust, you're off to a good start because ultimately law is merely the servant of justice, and if you wish to rebel against an unjust law or practice you'll often find many supporters.
Rights have a significant moral dimension as well as a legal one, so just because someone denies the existence of your rights doesn't mean you have to obey them. You can defy or subvert their authority, and if your intentions are pure then you should. By pure I mean not being a hypocrite; the broadening of your individual rights is not predicated on the shrinkage of someone else's.
