The West (with the USA as its effective center) and Islam are both huge empires, between them (directly or indirectly) shaping the lives of a significant proportion of the human race. Both can be brutal and oppressive, and both exploit the weak for the benefit of the strong.
However, there is one crucial difference that stands out.
The West will allow its citizens to live as Muslims. Islam will not allow its citizens to live as Westerners.
