What if someone went to jail for civil disobedience, i.e. protesting against some injustice they see in our government?

Stripping them of the right to vote, along with all of the other privileges (mostly by convention, rather than by statute) one loses once convicted of a felony, would be a really convenient way for those in power to insure that their critics are powerless.

Several of my friends have faced felony charges for various protest activities (non-violent civil disobedience, mostly). It is not at all theoretical that our state would use the criminal justice system to effectively muzzle critics; a combination of jail time, plus the crippling effect a felony has on your ability to work and earn a living, plus the inability to vote, plus the ability of the justice system to suck you back in much more easily from the moment you've been convicted of a felony, adds up to a very powerful set of tools for silencing dissent.
