I think you are a bit confused. Carson is running for president of the US, not pastor of your church or president of your national assembly.
Your argument is both ugly and foolish.
The subject of religion or the lack of it in presidential candidates and campaigns has been debated since the time of the founders.
In more recent times, recall the intense debates about JFK's Catholicism, and right here on the pages on this forum, the intense back-and forths on presidential candidate Mitt Romney's Mormonism.
Speculative comments on Obama's religious leanings (Christian or Muslim?) or his lack of any leaning at all pops up here regularly and have been for almost eight years.
Furthermore, I've seen no comment from you on the attacks against Donald Trump questioning his Christianity, spinning/distorting his comments on confession and deriding his and his family's membership in NYC's Marble Collegiate Church, one of the oldest continuous Protestant congregations in Northern America (1628).
Pray give me one good reason why Ben Carson's affiliation with a denomination regarded in many theological circles as cultish should not be discussed here.
The subject was brought up by me only as it relates to the primary, namely (and this is the whole point), the nation-wide evangelical voting block obviously is largely unaware that the pious Carson is NOT one with them theology-wise...a fact that Carson carefully avoids bringing up. Nor does the enemedia promoting Carson touch on it, either, although it has no compunctions dissecting and snarking on Trump's denominational affiliation.
Give me one good intellectual reason why this information (important to many folks in a primary even if not to you) is off-limits for legitimate discussion here on FR and I will cease and desist.
