I understand where you are coming from, and i hope you dont misunderstand me when i say that your defination reflects a departure from the conventional understanding of oppression in islam.
It seems to me that you are more concerned with the individual than society.While islam like judaism preaches certain moral codes ( some of which may go against the individual freedom which we living in the west so much cherish).Violation of these God-given codes is likely to invite what we may consider harsh retribution.This could involve use of coercion, force and “subjecting the populace to your subjective understanding of religion and expecting that diversion from that is grounds for violent correction” this quote of yours is an essential part of “forbidding evil” in religion.This is not simply a feature of the "bad apples’ amongst the religious or pseudoreligious class e.g talibs but a feature of all relgious reformers past and present.SOme of which are highly regarded amongst various groups of muslims.
The big question remains ( as PA hinted) whose version of religion is to be followed ? and thats the argument used to advocate the seperation of religion and state.However its not as hard as one might think it is, the vast majority of muslims claim to follow one fiqah or more and they could be judged according to the rules of their respective fiqahs.
