Contrary will do, but contrarian is better. I take a contrary view to a post or posts to find out more, to challenge what appear to me to be assumptions, and so on. It's a common discursive device. Where people actually engage rather than talking down to me and telling me what I think, they quite often enhance and modify my view. Which is the whole point of the exercise.
The duck film was more a comment on the kind of responses my posts get, the tone of responses that seem to lecture me, that seem angry with me, that tell me what sort of person I am rather than debating the issue, that snipe at me, and so on. Me being a duck getting unphased by it all is what I aim at. I hope that helps people's understanding (faint hope! I must admit).
I intend (typed untend first; freudian skip? blast! slip (onehanded typing as right is out of commission)) to find out more about JRM as well as following moggmentum.
