the right to vote

There are property rights. There is no right to steal. There is no right to vote to steal. A majority voting to steal is no different in principle than a majority voting for a lynching."

George Reisman,
"Under Siege: Voting Rights of Felons or Property Rights of Citizens?"

Reisman's point is important and well stated (especially for someone who rejects libertarian anarchism), but there's also an important comment from "David C":

While I don't like the notion of anybody voting who would tend to want to use government to take away my freedoms, it seems to me like it just leaves way too much subjective room for the government to decide who can vote and who can't. Just how long would it be before it would extend over to unauthorized drug possession, then to unauthorized firearms ownership, then to breaking tax law, then to "unruly" protesters.
