I am reminded here of Chesterton’s masterful Negative and Positive Morality, in which he writes, correctly, that “to give the answer “yes” to one question is to imply the answer “no” to another question.” In fact, this is one of the Aristotle’s three rules of thought: the law of the excluded middle, which flows out of another—that of non-contradiction. If Socrates is mortal, he is not immortal; if Socrates is immortal, he is not mortal.
What does it mean to be the party of no? No to what? It cannot be no to everything, since, in fact, Republicans are quite up front about what they are in favor of: pro-gun, pro-capitalism, pro-life, pro-God, pro-marriage, and so on.
Notice that these are universal principles. What are liberals pro? Pro-gay, pro-government, pro-welfare, pro-abortion, and so on. These are all interest groups: not all of us are homosexuals, not all of us work for the government, not all of us want handouts, and not all of us want abortions (although 1 million of us do per year, pray for us). Liberals are pro-certain-people. Conservatives are pro-certain-ideas. Everyone, whether they like it or not, is for certain things and against certain others.
Now, of course, the typical liberal response to this argument—that stopping legislation is neither good nor bad, but depends on what it is we are stopping—is to try to use their own divisiveness to make us seem divisive (e.g. you oppose our divisive policy of favoritism to homosexuals, ergo you are a bigot). This is obviously a fallacy to any of us upon reflection, but the whole point, and fun of holding liberal clichés under a microscope, is that it makes them easier to spot in their natural habitat of Yale, Princeton, Harvard, Howard University and CNN.
