What Does ISIS Demand From Christians ???

According to this report, ISIS is making the following demands on Christians:

The Islamist militants, now occupying large regions of Iraq and Syria, have issued an ultimatum to the remaining Iraqi Christians in the city of Mosul: accept Islam, pay extra taxes to Islamic Sharia courts, or face "death by the sword."

Are these demands not similar (if not identical) to the demands being made on Christians in the US by Obama ad-Dajjal?

• Accept his view on what is and is not an acceptable religious practice or belief (e.g., birth control);
• Pay extra taxes to support his views on those religious practices or beliefs (e.g., the ObamaDon'tCare Program taxes); or
• Face the penalties he decides to impose on you, up to and including death (e.g., the extrajudicial killing of Anwar al-Awlaki and son).

Granted, most Americans will not consider this to be a valid comparison, but the point I am trying to make is that fundamentally many of ISIS's demands are very similar to what we Americans are now subjected to by our own government.

I post this to inform. I do not admire or support ISIS or the Islamic State.
