Maybe. In the case of the Comicsgaters, they seem to be pretty focused on their single target (Marvel) in regards to being anti-diversity. One member who I infrequently follow the work of (trying to understand the mindset and all that) was doing his thing years before Comicsgate "officially" started. However, I have seen some overlap -- the guy I mentioned has been attacking Star Wars and certain creators since Last Jedi and has made statements that lead me to believe that he's very pro Gamergate. So, he does seem to be a equal opportunist in terms of finding targets to harass because of the SJW conspiracy theory (the thing that really gets me is that most the "SJW" stuff -- which, incidentally, is an extremely meaningless statement -- are mostly elements that have been in the franchise long before Disney took it over, if not the very beginning. Conversely, I did once hear a podcast interview where some pro comic writers wondered if Comicsgate was specifically targeting Marvel because it had weaker sales and therefore could make their claims that progressiveness was destroying the industry seem more plausible. I don't know if that's true or not, but I do have to concede that it seems like a very strange happenstance that so man fan hate groups with similar worldviews and agendas are popping up at the same time.
