I'm not sure how useful of a description for revolutionaries this is. They are not necessarily lonely wolfs as I interpret the article, they might deeply care or not about things like diversity and they are certainly able to do a lot of politicking. Unless you want to completely redefine the term. For me the difference comes more down to, as with the conflicts within lots of political groups in history: reformists vs non-reformists. The former advocating the reform of an existing system or institution whereas the others believe the right approach is abolition and replacement. You could also add reactionaries, those that want to go back how things used to be. Neither of which is universally true I think, more often than not it is a mix. But I don't think you get very far trying to mix the extremes from either side.
