Fact is that these are populaces that were denied legal, effective means to affect change of government in every case listed; so they were forced to take illegal approaches to advance their concerns.
this is only true in some cases, in others you're damn right there is no legal means for a minority to establish a communist form of government or implement Shari'a law. In your view the government is always the villian, and the insurgent always has a just cause. That is baloney.
