Those among which a believer has to practice dissimulation are bad people!.
Brief description
Dissimulation and concealing ideas usually arises when a selfish majority
of the society prevent the righteous minority to express their thoughts and
divulge their ideas. Surely, such society will not be prosperous. In an Islamic
and humanitarian society, the righteous people should have the right of
divulging their ideas for public opinions, and common people should not hinder
them, and rather respect freedom of thought in the reforming aspects and
provide facilities for training and making fruitful these thoughts.
