Um, again, shouldn't their religions be irrelevant? Regardless of whether this religion is proferred for public appearance, or secretly practiced in private, or even (falsely?) assumed by public consensus?
I don't think that Sarah Palin's "religion" is irrelevant, or, for that matter, that Mike Huckabee's "religion" is irrelevant.
In the case of Sarah Palin, she expressed doubt about whether life developed through evolution by means of natural selection. To me, that casts doubt about her ability to reason logically, and that's relevant.
In the case of Mike Huckabee, he expressed the intent of making America a Christian nation even if it meant amending, or breaking, the Constitution. If that isn't relevant, I don't know what is.
It's become a cliche to say that only the terrorists were responsible for 9/11, not Muslims in general. That is a fact, as far as it goes... but, sadly, it's also a half-truth. Islam is
not just a highly personal faith-based relationship between the believer and God.
One can look at the behavior of Muslims in several majority-Muslim countries with significant non-Muslim minorities to observe that Shari'a Law, which denies equal rights to non-Muslims, is believed to be a part of Islam by a large proportion of Muslims.
You wouldn't blame a black voter for not voting for any white politician who he suspected of believing that black people must "know their place", and who would change the legal system so that the testimony of any black person must be disregarded if that of a white person contradicts it.
This state of affairs existed in some of the southern states of the United States under segregation.
Well, in Islamic countries, that's how non-Muslims are treated. There's something blameworthy in not being willing to be made subject to treatment like
that? I don't think so.
Islam is not just another religion. In its two major forms, it exhorts its followers to commit aggression against non-Muslims.
Now, maybe someday an Ahmadiyya Muslim, or even an Ismaili, might be elected President. I suspect however, that this, like the election of a Jewish President, will have to wait until the Middle East situation gets a little less explosive.
Right now, it's also going to be important that the President be able to respond to this particular major area of foreign policy in an unbiased manner that will put American interests first. Not having any personal investment in the situation is, therefore, something not unreasonable to ask for.
