That's correct. Actually, for most of these Azerbaijani activists, even asking for the implementation of the constitution has got them arrested, detained, tortured, kidnapped, and killed. Azerbaijani activists are operating within very unfair laws of the Iranian government. Their movement is totally peaceful, and they are not violent.
The first thing they ask for is implementation of the constitution. Not only is the constitution not implemented, but asking for implementation can get you to prison, as in the case of Abbas Lisani. He has served months for asking for implementation of articles 15 and 19 of the Iranian constitution.
