Those things which you describe so casually as your own preferred behaviors are seen by those with a lesswrong mindset as disengenuity and the abuse of the dark arts.

It is not dark arts if you are honest about what you are doing.

What I am often doing is exploring various viewpoints by taking the position of someone who would be emotionally attached to it and convinced about it. I also use the opponents arguments against the opponent if it shows that it cuts both ways. I don't see why that would be a problem, especially since I always admitted that I am doing that. See for example this comment from 2010.
