The devil doesn't need any more advocates.

Evidently the construct of the devil does because humanity can help but setup complex situations that require a balanced approach rather than only looking at things one way.

In that case, you can explain the nuance and offer a more balanced viewpoint, without invoking the devil as an accountability sink. Your words should stand on their own merits. (To be fair, you did this! I'm just saying you shouldn't preface your words with a trite phrase that signals you'll be lobbing cheap logic over the wall and disavowing responsibility for your words if the logic proves faulty.)

At least to me it sounds like you just have problems with the incorrect use of the devils advocate by some people in the first place, of which I would actually hope you understand its use in rhetoric.

At least in the common HN discussion you nearly have to use its form when talking in an approving manner of things like regulation or unions because it goes against the Holy Church of Capitalism, lest you be punished by the mighty downvote button for heresy.
