Yes, anything that involves religion can never be short.
Actually, there is a trend of fundamentalism developing. It's an international trend; it's not just an Ethiopian phenomenon, but it is all over. Muslims everywhere have tried to harden their positions. That is also reflected in Ethiopia.
When I grew up, I didn't see Muslim women covering their heads. Now it is the thing to do for Muslim women. It's a general trend, the way I see it. But Saudi Arabia does play a role, in the sense of encouraging the Muslim population to assert itself, possibly. This is what makes it a little more different from the past. Mosques are being built everywhere in major Ethiopian cities. There were mosques in the past, but not as many as there are now.
However, the population is pretty well integrated with each other; Christians, Muslims, and even the very few Jews live together really. There is much more cooperation and much more integration in the population.
Article 29 of the constitution of this regime allows any ethnic group to secede. This regime cursed the flag that Ethiopians grew up with, but people are supporting each other and are sitting strong. Really, nobody ever makes a claim to secede.
Of course, there is the Ogaden movement and the Oromo movement. If you were to handle it politically, these movements could be pacified and could become good players in society. But the lack of democracy in the current system is causing much to be astir, and would even in the most established societies, I imagine.
Thank you for asking.
