It very much is a wider problem.
Afghanistan has problems with Shia groups facing discrimination in certain local areas. It's much more homogenous, though.
Pakistan, which is almost entirely Sunni, minority Shia, has huge problems.
Iran is terrible with respect to the small number of Sunnis it has.
The Bahá'í, who we haven't talked about at all here, is a very small population. The Bahá'í of Indonesia are facing a lot of problems with these groups as well, but the Bahá'í face far worse problems in Iran and Egypt than they do in Indonesia. Just today, the Egyptians are debating their constitution, and there are a lot of issues they have to sort out as well.
This is by no means just Indonesia. This is a problem you see in all of these countries, which have Shia, Sunni, and a small number of other faiths, such as Bahá'í, Hindus, and Sikhs.
