If one is prostrate to the truth, then rebuttals to opponents simply write themselves. Largely, they just consist of paraphrases or 1 or 2 logical steps.
Compare mathematics and the political sciences - it's quite striking. In mathematics, in physics, people are concerned with what you say, not with your certification. But in order to speak about social reality, you must have the proper credentials, particularly if you depart from the accepted framework of thinking. Generally speaking, it seems fair to say that the richer the intellectual substance of a field, the less there is a concern for credentials, and the greater is the concern for content. One might even argue that to deal with substantive issues in the ideological disciplines may be a dangerous thing, because these disciplines are not simply concerned with discovering and explaining the facts as they are; rather, they tend to present these facts and interpret them in a manner that conforms to certain ideological requirements, and to become dangerous to established interests if they do not do so.
Your stuff will start to puff up. Your paragraphs will start to get rotund with all the things you could say if you really wanted, but you can only hint. That's bad. It's bad intellectually and I think it's bad morally. It means that you become.. your contract is no longer with your readers. What I try and do, and the reason I write in longhand and write in isolation, is to say "The only person I have a deal with is the person who might read this. And I'll give them my best, and I don't care what the editor thinks, the advertising department thinks, friends and colleagues think." You try and live, as it were, as if none of these people counted. "What's the best account I can give for customers of this." Most of Washington punditry is nothing of the kind, it's... private letters written to other pundits and appearing in public space.
You rarely get the satisfaction in intellectual life where the person who is wrong has to acknowledge and grow from the experience of having been self-deceived for so long.
