If we cling to the institution of Islam, then we tend to defend it against whatever we see as a danger to it, so because of this we see now that many people are defending states, defending territories, defending everything institutional in the belief that they defend Islam.
We should be proud that our Prophet came into the world with the message of Islam to change it for the better, and not for the worse, or to keep things as they are.
We have shown that Islam can rule the world perfectly for 14 centuries, and during this time of Muslim power we did not borrow ideas like democracy from others, so why do we need to learn democracy from them now?
To do Mohammed justice, his main attack was against the idolatries of Asia. Only he thought, just as the Arians did and just as the Unitarians do, that he could attack them better with a greater approximation to plain theism. What distinguishes his heresy from anything like an Arian or Albigensian heresy is that, as it sprang up on the borders of Christendom, it could spread outwards to a barbaric world.
