A libertarian view of rights, held by the Founding Fathers, is that they are constraints on what the government can do *to* you (such as restricting your speech, worship, or ownership of firearms) and not mandates of what the government must do *for* you. The Bill of Rights in the U.S. constitution contains negative rights. I don't favor adding positive rights to U.S. constitution, including the rights advocated by James Meredith.
Many state constitutions have laws guaranteeing the right to a free public education. Even these can be problematic, because they have often been used by judges to strike down voucher programs and because some judges have used such rights to mandate spending levels, which is a political decision best left to elected legislators.
