Nice attempt at a red herring. I didn't use the word democracy. I said representative government, didn't I? A good representative government has checks in it to reduce the effect of tyranny of the majority. That being said, there is still nothing wrong with a self-governing people enacting moral issues into law.
With the inevitable trampling of rights of the minority. Iran's leadership is in power at the will of the people, would you like to go live there and preach Christianity? Problem is that's considered immoral to them, so you'd be jailed.
