Hizbut Tahrir Indonesia wants a caliphate. Its members believe democracy is bad. Because "it brings you secularism, an arch enemy of Sharia".
Then enter Din Syamsuddin, the chairman of Muhammadiyah. He says caliphate system is good and "we shouldn't reject it". But he also says, "[Caliphate system] should not undermine the inclusivism and and pluralism of the nation" and it should conform with Pancasila.
We know Pancasila is almost identical with democracy. 'Inclusivism' and 'pluralism' are the children of democracy, or so we were taught in schools.
So, Din, apparently you have to choose one. You can't have 'em both, Mister. Trick or treat?
