I appreciate your commendation of individual liberty, but it is antithetical to allow the federal government to regulate state laws so that they can control something which they had no authority to control in the first place. The idea that the federal government can intervene with state laws in order to "protect" the bill of rights is what brought us the whole mess of trying to define "religion" as it applies to establishment cases in the public school system. All of a sudden, we have Supreme Court cases trying to define when you have a right to free speech, and everything becomes uniform across the nation instead of being solved at a local level. Things like "Sherbert v. Verner come to mind as cases in which the fed intervened in order to define individual liberty and all of a sudden got involved in trying to define things on a federal level, which ultimately takes power away from the individual. I happen to believe the 14th amendment does not give the federal government such authority, but it is good to know your rights when it affects you. If you study court cases and the constitution in any length, you'll see that "Congress" becoming defined as all levels of government is what pretty much screwed up our system and gave the feds power to manipulate our personal lives. If you care about liberty, you should be opposed to the bill of rights being protected by the federal government. It is a limitation AGAINST the federal government for a reason. Ultimately, the way the Constitution is set up, it is so that the federal government should have little effect on your personal life. It is much easier to control state power at a state or local level, and ultimately, the state constitutions are all that should really matter to you in the place where you live.
If the bill of rights is what allows the federal government to decide what your rights are, then it is best to not have a bill of rights. We should have a bill of limitations, not something that gives the federal government a say in what you do at school and what constitutes speech. Read and know your state constitution, and that will ultimately be what you should look out for. Of course, now, state Constitutions are almost irrelevant, but minus the federal monopoly on individual liberty issues, it should really be all that's relevant to your life in the most immediate sense.
