In order to argue civil liberties issues, you will need to present your position as being more conservative than the opposing viewpoint. Remember that following the Constitution is the most conservative position possible. Put your opposition on the defensive as much and as often as possible by asking questions like "how can invading people's privacy possibly be considered conservative?", "how can unfunded mandates (like real id, for example) be considered conservative?", "as Republicans, shouldn't we be working to decrease the size of government and lessen government intrusion into our lives, rather than do the opposite?", and "how can we implement what you propose without raising taxes and going against what our party is supposed to stand for?". You will need to question that the opposing viewpoint is the conservative position (isn't attempting to solve this problem with bigger government a liberal's viewpoint?). Be prepared for the attacks that will be thrown your way, try to think of what the opposing argument will be for the issues that you plan to raise. If you are not prepared to argue that your position is actually the truly conservative position, you will end up being called a liberal and marginalized. Try to avoid mentioning RP, and if anyone asks you who you support for President, duck the question if possible by simply stating that you voted in the primaries for the candidate that you thought was the most conservative - if you are further pressed, simply mention that the nomination has been decided, so the question is a moot point - if your are pressed further than that, state that it's none of your business, that the question is irrelevant because McWar got the nomination, and ask them why they are asking. If you are asked if you support McWar, again duck the question with the response of "well, he IS who the party nominated, isn't he?"
