Back in Suharto's era, Indonesians were not these fanatics like today. In fact, there were many who didn't even wear hijabs. The majority still not that fanatics, I saw a family with the wife wearing hijab, drinking beers not too long ago. In nightclubs, many are also drinking alcohol, of course not wearing hijabs. Strangely, they have no problem drinking alcohol, but pork is a no no for the most, though I do know some who eat pork secretly, but very very few.
The hardliners do grow significantly, especially for the past 15 years or so. The Saudi used to finance the madrasahs in Indonesia, and since then the hardliners are growing like plague. They even want to discard their own culture to embrace Arab's culture, which is insane in my opinion.
That's why when China cracked down on the foreign influence on the Chinese muslims, I applauded it. And it seems Saudi under MBS also want to cut back on financing extremists.
