I understand your point, but if offering opinions from one political camp is viewed as 'trolling' by the others, then I would say we need to fix our approach to discourse.
From my point of view, if the articles are consistently always going to have the same sort of political bias, then a subset of those articles are going to have taken an unreasonable position - and it's those unreasonable articles that will troll people all the more. Unless, that is, the specific political bias chosen results in many more objectively reasonable and correct articles, but I don't think we're anywhere near that point yet with modern small-L liberalism.
At least some of the "fixing of discourse" has to come from the media outlets themselves. They can't continue to pit political camps against each other by outputting biased content, and then just point the finger at whichever political side they're unaligned with.
