I remember - when applying for Iranian visas, we received a booklet at the embassy ... it said how great the system in Iran is, explaining the capitalism is dead and the only way for the western countries is islamic revolution .... and it also had a chapter FREEDOM OF RELIGION IN IRAN... it explained, that there is a freedom of worship in Iran, because anybody can abandon his religion and embrace Islam ....
Looking at it this way - WTBS also supports freedom to change ones religion - anybody can leave former religion and join WTBS!
