So If liberals are in favor of Illegal Immigration and amnesty, why should the U.S. even have an immigration laws in the first place? I see a lot of Liberals not really liking the idea of enforcing that law or really even acknowledging it too often, but often are in favor of protecting Illegal Immigration. So if this is the case, why should people even bother legally immigrating?  why even have the law if it is such a controversial issue?
