That's true and I am but many Republicans and Tea Party types are there just for low taxes. They don't see anything else as being important, and certainly not lifestyle choices (depraved as these may be). These are also the type who say don't let an issue like abortion get in the way of electing our candidate (Scott Brown type). Basically I steer clear of any group unless pro-life and traditional family values are at the top of the signboard.
And that's what's wrong with a lot of the self-proclaimed Tea Party movement.
Let's face it - if you're only for half of conservatism, then you're not for conservatism. Conservatism is a self-contained, all-encompassing worldview, rather than just a "made for the ballot" laundry list of policy positions. Conservatism stands for the rule of law (constitutionalism), fiscal responsibility, strong national defence, AND traditional values because all of these things are interrelated. To only have one or two of them is to merely have a cannibalised shadow of conservatism - and the depth of understanding of the reasoning for why conservatism is what is is simply will not be there. This is ultimately why libertarianism fails as a coherent worldview. They want the freedom, but not, ultimately, the responsibility and moral grounding that must come with it. Our Founders understood that these must go together, though many modern libertarians who claim the Founders as their ideological forebearers do not.
