Convert to Islam, or die.

If I remember correctly, the choices aren't that strict when coming under Islamic rule.

There is a third option, dhimmitude.

This state of being gives allowance to those who refuse to convert, but with a price, their freedoms. Those under dhimmitude can live amongst Muslim society, but are treated and considered second-class citizens. Laws for dhimmis are much harsher than laws for muslims, miscegnation is out of the question, and sometimes, in the worst case, you must wear identification on your person to show to the world that you aren't a muslim.

Sounds attractive, no?

Jam it back in, in the dark.
