Earlier quoted context omitted.
Being intolerant to violent intolerance is not enough. Tolerating minority disenfranchisement also leads to the death of tolerance.
What do you call disenfranchisement?
This can take many forms. Virtually the entire citizenry can be denied the right to vote, as in autocracy. Poll taxes disenfranchise the poor. The combination of felony disenfranchisement and racial disparities in enforcement of criminal laws yields a situation where racial minorities are disenfranchised as a group.
Other shenanigans can limit people's choices, such as the restriction of candidates in Iran. Of course the first-past-the-post system used in the US also restricts choice in some ways... But "disenfranchisement", I'd say, specifically pertains to denying people the right to vote.
