Truth With/out Love

A question I would like to raise in response to this CNN link, sent by Gregory Laughlin, is how are Christians to express love with truth, as opposed to truth without love, as is claimed by this manifesto to be released on Wednesday. It addresses once again the failure of certain evangelicals "(religious right"?) to engage the culture properly, with political implications. Some would argue that when it comes to expressing love in the forum of public discourse, the best one can do is to simply tell the truth. Have political candidates and legislators and public officials routinely been criticized for arguing their policies or presenting facts without love? Of course Christians are called to the speak the truth in  love. (How do you do that on a news program?) Should we look to the manifesto when it comes out for some clues on how to express truth with love?
