In history they didn't have video games, porn, or mass surveillance of what you and your angry friends are getting up to. I would not expect things to play out by any historical pattern.
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.
They had plenty of porn like opportunities. Prostitutes are known throughout history. Usually a double standard where the males were accepted but females not
ask a historian... my guess is no, but sleeping with a girl is better than porn if you get that option. we also don't know what 'exotic dancing' opportunities the 'common man' got.
In historical times, rulers would also murder millions of people on suspicion of disloyalty. I think you overestimate the impact of video games and porn. Even if what you're saying is right, it's not better than some kind of violent correction. The trouble is that pushing young men to the point where violence is the answer wipes out all the rules. There will probably be a lot of collateral damage.
