What is wrong with having a Muslim as president?

[Koga No Goshi]

Nonsense, islam is imperialistic in nature, there will be expected a lot from an islamic president when dealing with the muslim world. He will be much more vulnerable for moral blackmail, and so will the governments of muslim countries when a muslim president is sitting in the US. Think of the international arena and count the ways of why it is a very very bad idea.

Christianity can't have exactly the same case made against it? I have some ancestors who would like a word with you. And no, they're not from the Middle East.

The U.S. calls itself a "Christian country", Christianity was the overtly given justification for the complete conquest of at least two continents of the planet, and the eradication of much of the existing populations. So coming from a western culture, European post-Christian society, I'd be careful about throwing accusations of religiously-based imperialism around at other people.
