The linked article is so misleading that I wouldn't try to derive any true statements about reality from it. It fails to mention any legitimate points of their opponents, and then concludes they don't have any. Five minutes on google would probably give better results.

(I strongly bite my tongue here to avoid going into specific details, but I spent the last month observing GamerGate and it is fascinating to watch how good job can media do to prevent some information from being ever mentioned, and how all information about this topic ultimately comes from the same two or three people.)

One thing, though. The article is pushing a narrative "all our opponents are actually the same" while in fact the only thing conecting them is, well, being opponents of one specific group in one specific topic. For example, there are many feminists in the GamerGate movement (no, Christina Hoff Sommers is not the only example), and also there are many people believing that feminism and men's rights are not contradictory. So the whole paradigm of "dark forces are rising" may be just a convenient excuse to explain away some specific failures or a specific group.
