The Far Right will reliably target any community that has 1) a large, white, male population, 2) whose niche interests allow them to feel vaguely marginalized, and 3) who are not used to progressive critique of said interests. This isn’t to say progressive critique doesn’t exist, or hasn’t been baked into the property from the beginning, but that it has been, so far, easy for white guys to ignore. As such, progressives within that community probably don’t talk politics much, and women and minorities are perfectly welcome to post, same as anyone, but just, you know, don’t, don’t make identity politics, you know, like, a thing.
Given Gabe’s proclivities, he’s probably already in a number of fan communities where he can geek out and not get teased. And this is where the Far Right will go looking for him.
Communities are at their most vulnerable to infiltration at times of political discord. This can happen naturally - say, a new property in the fandom has a Black protagonist - or it can be provoked - say, a bunch of channers join the forum and say provocative things about race to get people arguing - or both. Left to its own devices, the community might sort out its differences and maybe even come out more progressive than they started. But, with the right pressure applied in the right moment, these communities can devolve into arguments about the need to remove a nebulously-defined “politics” from the conversation.
The adage about bros on the internet is “‘political’ means anything I disagree with,” but it’d be more accurate to say, here, “‘political’ means anything on which the community disagrees.” For instance, “Nazis are bad” is an apolitical statement because everyone in the community agrees. It’s common sense, and therefore neutral. But, paradoxically, “Nazis are good” is also apolitical; because “Nazis are bad” is the consensus, “Nazis are good” must be just an edgy joke, and, even if not, the community already believes the opposite, so the statement is harmless. Tolerable. However, “feminism is good” is a political statement, because the community hasn’t reached consensus. It is debatable, and therefore political, and you should stop talking about it. And making political arguments, no matter how rational, is having an agenda, and having an agenda is ruining the community.
(Now, it is curious how the things that provoke the most disagreement tend to be whichever ones make white dudes uncomfortable. One of life’s great, unanswerable mysteries.)
You can gather where this is going: a community that doesn’t tolerate progressivism but does tolerate Nazism is going to start collecting Nazis, Nazis whose goal is to drive a wedge between the community and the Left. Once the Left acknowledges, “Hey, your community’s developing a Nazi problem,” the Nazis - who are, remember, trusted, apolitical members of the community who might just be kidding about all the Nazi shit - say, “Did you hear that, guys?! Those cultural Marxists just called all of us Nazis!” Wedge. Similarly, any community members who say, “but Nazis though” are framed as infiltrators pushing an agenda, even if they’ve been there longer than the Nazis have. They get the wedge, too.
This is how fandoms radicalize. They are built as - yeah, I’ll say it - safe spaces for nerds, weebs, and furries, and are told that the Left is a threat to their safety. Given a choice between leaving a community that has mattered to him for years and simply adjusting to the community’s shifting politics, the assumption is that Gabe will stay. This assumption is right often enough that a lot of fandoms have been colonized.
What is true of both of these methods - Gabe finding the Right or the Right finding him - is that Gabe does not come nor stay for the ideology. He’s here for the community, the sense of belonging, of being with his people, of having his fears validated and his enjoyment shared. The ideology is simply the price of admission.
