Atanu describes how Singapore controls religious bigotry and intolerance. Cable TV must be very different with no preaching!
Freedom of religion is guaranteed in Singapore but freedom to proselytize is not. Proselytizing essentially says that my religion is better than your religion and that if you don’t accept my god as the One True Savior(TM), you will rot in hell that my god has specially prepared for you. This sows seeds of discord in society and soon the newly converted start asking for special treatment and handouts and in the limiting case, when the bunch grows sufficiently large, ask for a separate state of their own because they cannot bear to live with the other people who are destined to go to hell.
So Singapore is strict about proselytizing. In keeping with their policy of discouraging that anti-social behavior, they caught a meek little Catholic lady who was going door to door peddling her religion and threw her into jail after she was found guilty by the courts. Then they publicized the event. This sent the message to all religious bigots who follow the dictates of their own hearts that bigotry is not ok.
They took care of the mullahs as well. Got them together and told them that if they even make a peep in their weekly religious sermons promoting killing and terrorism, they will have their butts in the sling. Live and let live was the message they got and as rational humans, the mullahs got in line. The last time they had communal unrest was sometime in the late 1960s.
