Controversial/political correct/woke/ topics will be clarified by nostr plebs first hand. 
Bonus of importing Wikipedia is that you have shit load of well organized general humanity knowledge which is not that subjective or controversial (animals, plants, countries data, places, all that normal stuff which is also present in old fashioned paper encyclopedia). 
Filling that up even considering nostr growing adoption will take years. 
I'd vote for sucking Wikipedia but marking all imported articles with different color and then mark with new color pieces of article that was already changed by plebs with change history (similar to github repo).
