Yeah i understand your point but with all probability video games have very little to do with the rise of extremism i think. It's much more i think about more and more people feeling they don't really fit into the mainstream world for whatever reasons and start looking for alternative alignment points.
Let's look at e.g. islamism, probably the biggest extremist direction nowadays. The role in video games in that is probably negligible. Much more like the fact that secular Middle Eastern autocracies started to collapse for multiple reasons, people started looking for alternatives and they've found the next biggest alternative to secularism. The same with people living in the West, many of them felt they just won't fit in a consumerist world and found the strongest alternative which in their case was islamism.
I think it's very similar mechanically with other extremisms too. So you always have to ask WHY these people feel themselves unfit for this world or in reverse the world unfit for them? As if they feel so they'll find some extremism for themselves eventually let it be some form of religious fanatism, communism, liberal marxism, fascism, racial supremacism, whatever.
But again it's very off so excuse me once more
Speaking of extremism, the future of the world is fascism, this ideology will dominate the scene once again, like a wolf in sheep's clothing, they will speak of peace, a kind of environmental activism with the purpose of uniting the nations of the world for a supposed common good(In this case it is theirs, the fascists dressed as priests of peace and little blond Swedish girls, not ours). As a result the world will fall into the graces of a hidden fascism.
You can't relativize the sovereignty of a nation without a good reason and fascists are experts at that. The speech today is: "We need to preserve the Amazon, they are destroying the lungs of the world". Just look at the case of that very kind North American, who proposed the creation of an ecological preservation corridor(I think I've heard this word somewhere else and some other time, was it a "Corridor"? "Polish"? no, it must be just my imagination), passing mainly through the Brazilian, Colombian, Venezuelan Amazon. So he basically proposes that Brazil, Venezuela, Colombia and others give up extensive parts of their territory for a supposedly greater good(which is certainly not that of South Americans).
This is basically how modern fascists act, especially one that I have the displeasure of being a compatriot(He sits on a throne in Rome as a Roman emperor). Fascism is a word relative to the Latin term "Fascis", it has everything to do with Rome, the Roman Empire was fascist for example, it is the power and total control of the state over everything and everyone, and the ancient European kingdoms that were greatly influenced by Roman culture, many nations imitated the Roman state system, love to display a Great Eagle on their coats of arms, flags and national symbols.
Another great purpose of fascism is also to recreate the Roman empire and they will succeed sooner or later. Besides being governed by good fascist systems dressed as democrats, the Europeans and some other world powers are excellent ecologists, their history of environmental preservation makes them the best on the subject, they have preserved their forests very well, especially the French. Nobody better than Europeans to talk about environmental preservation, they have devastated about 99.7% of their original forests and now want to teach the South Americans how to preserve the Amazon forest that is practically intact for 500 years.
Where did all this wood go? Oh, it must have been in the countless wooden ships built between the 15th and 19th centuries, after all, you couldn't cross the oceans swimming. How do you think the Europeans arrived in America? It certainly wasn't mounted on a dromedary.
Look on the bright side, they destroyed their forests and woods for the common good(which certainly was not that of the Indians either). The North American activists are the best humorists of all, after all, they, the North Americans, were the ones who most preserved Indian tribes. There must be one Indian for every 10 people in the United States (only if it's at Disneyland, all pale face actors with their skin painted red).
