Religious tolerance went wrong. It's always subtle. It starts first with the loud prayers coming from mosques, you diam diam and "tolerate" then later it is assumed it is their right. Then comes the puasa thing, where they tell you it is disrespectful to eat in front of a fasting muslim, and you obey. Then comes halal issue, make a non-Muslim factory shutdown because of some unconfirmed material in chocolate, then people diam diam and take it up the tailpipe.

It snowballs, and eventually, you have extremism.

Religious INtolerance and mutual respect is the key to religious harmony.
