The problem is that the world is full of diverse people who all have different opinions and beliefs on how things should work.
I visited Thailand three times, it is around a Buddhism community. Quite different from the Christian communities you'd see in the USA. Christians are a small minority in Thailand and there are more Muslim and Chinese than Christian. Each one has their own community. I visited a Muslim community because one of my wife's cousins had married a Muslim man. They were very nice to me and my family. Five times a day a car would loud speakers would drive around for their daily prayer. There was no pork or alcohol for sale before their religion forbids it. They cut their chicken differently from us, but it tastes good.
I am not sure if they'd go for a secular community. They already got one of their own religious communities and have done this sort of thing for most of their lives.
Moving away from religion and becoming secular is a western thing not an eastern thing.
I see the Dawkins Foundation was mentioned, a lot of times they criticize and attack religions when they could have used the resources to help out people in the community instead. Using hate instead of love, and then sometimes having to retract web pages when proven wrong like the Jesus is Horus thing or the Easter is Ishtar thing.
You have secular communities in the USA and UK, but they are small and limited.
Public schools in the USA got rid of religion, but didn't find anything to replace it to teach morals and ethics instead like critical thinking.
The problem is when you get rid of religion you get rid of a lot of good stuff too, and if you claim religion is bad and you get rid of it, it is like tossing the baby out with the bathwater. A lot of Christian charities did adoptions, and got attacked because they didn't support same sex marriage, so they went out of business and left a big hole to be filled. The same with Christian homeless shelters, many had to close down due to being attacked and criticized. There were no secular homeless shelters to replace them.
As the community moves away from religion and towards secularism, they have to replace the structure that was there by religious communities. It takes a lot of money to do that and a lot of volunteers.
