I agree that videogames and porn are effective pressure-release valves for this energy. Or perhaps sedatives is a better metaphor.
My pet theory about Gamergate was that it was in part a reaction from young men who felt disenfranchised by the offers mainstream society gave them. So they retreated to videogames and a virtual world where they could have some level of (virtual) success and esteem. And then when some women showed up there, they reacted with the anger you would expect from someone already driven out of one place and forced into a corner.
Even so, sedation and distraction only gets you so far. People want to feel that they have meaning and dignity in the real world, not just on their screens.
