A group of seven Bahá'ís, in prison since 2008, have been sentenced to 20 years of jail each. Those seven had some kind of informal leadership role, if I understand correctly (the usual Bahá'í administrative have been closed for years now). It is obvious that they are in prison for not having the officially approved belief. Any other accusation against them are but silly excuses.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
