On civility, note well the analysis by James D. Hunter, Evangelicals: The Coming Generation:
Evangelicals generally and the coming generation [younger evangelicals] particularly have adopted to various degrees an ethical code of political civility.  This compels them not only to be tolerant of others’ beliefs, opinions, and life-styles, but more importantly to be tolerable to others.  The critical dogma is not to offend but to be genteel and civil in social relations.  While their adoption of this ethic expresses itself politically, it expresses itself as a religious style as well….  In this latter sense, it entails a deemphasis on Evangelicalism’s more offensive aspects, such as accusations of heresy, sin, immorality, and paganism, and themes of judgment, divine wrath, damnation, and hell.  Anything that hints of moral or religious absolutism and intolerance is underplayed.  Indeed there is enormous social pressure to adapt to this code of civility.  As one national opinion survey showed, the predominant image of conservative Protestantism is still negative.  They are very often viewed as “overly strict on moral issues,” “closed minded,” “intolerant of others’ religious views,” and “fanatical about their own beliefs” and are believed to place “too harsh an emphasis on guilt, sin or judgment” and to be “too rigid and simplistic.”  This kind of characterization cannot help but create tremendous social constraints to be less strict, less fanatical, more open-minded, and so on.  (pp. 183-184).
…
… early Protestantism cultivated a fanatical devotion and adherence to faith and an incivility and intolerance toward any deviation, practical or theological.  “Knowing the truth” with calm and absolute certainty is in itself (according to contemporary standards) a brazen act of anti-intellectuality, arrogance, incivility, narrow-mindedness, and extremism.  Yet these things were intrinsic to the life of the believer.  The historical irony is that those cultural expressions that were symptomatic of early Protestantism’s moral energy and vitality are precisely those cultural expressions which, on the present scene, are despised by non-Evangelicals and are a source of embarrassment to Evangelicals themselves, particularly the coming generation.
