Keep Track

I guess the biggest problem I see is that some content may be commentary or opinionated, and you’d probably want to enforce what opinions are acceptable

I can totally see this being a problem, and the way I see of fixing this is by creating different categories of articles. One category could act encyclopedia/news-like, attempting to simply restate facts from an unbiased perspective(You might have one article that explains everything the current admin has done in relation to our nuclear arsenal, for example), whilst another category could act more like Wikipedia:Essays and essays/guides enjoyed/used by the community might be promoted to a third category of high quality guides and essays.

I think it may be hard to nail-down the scope of the project, and stuff like what are acceptable forms of resistance to write about.

I see this as a problem, much more then the first problem of yours I covered. I personally do not outsource my moral systems to laws or believe that because something is illegal it is always bad, but I also do not know if I would like to cover direct action. I think that if(when) fascism gets worse, direct action will begin to become necessary(if it is not already) so I am leaning on allowing the coverage of direct action, just not the more illegal-to-cover forms of it until fascism gets worse/the wiki is more secure.
