I was going to suggest Linux fans - of the libertarian variety - but it's hard to pin them down to a traditional left-right axis. They tend to be pro-business, or at least pro-capital, pro-ownership of capital, but the open source movement has parallels with utopian communism, and yet it exists so that trinket shops can more easily set up internet shopping portals. I suspect a world run by Linux fans would be totalitarian but neither left nor right; internationalist, but anglocentric, with absolutist views on crime (drugs legal; death penalty for almost everything else) and healthcare (don't get sick) and women's rights (women do not exist ergo they cannot have rights).
Could Linux fans take over the world? Huge chunks of the internet run on Linux and it only takes one man with technical know-how to do a lot of havoc, albeit that the same is true of one angry engineer with a digging machine or a chainsaw, but as with all IT / internet subcultures Linux fans are scattered widely across the world and have an unappealing set of evangelists, so they aren't ever likely to have mass appeal. They could rain bombs from the sky but not hold territory, to use a military metaphor.
I suppose you have to draw a distinction between subcultures that have a right-wing aspect, or that would be naturally aligned with the right wing, and subcultures that are explicitly right-wing. The entire Bitcoin / Cryptocurrency subculture is pro-capital and in that respect right-wing - I'm willing to bet that 99% of the members are young men who don't give a toss about universal healthcare or human rights, they just want money - but the same could probably be said of custom car enthusiasts, home AV enthusiasts, RC drone collectors, anything that involves men who are comfortable with having money. Are those groups likely to plant bombs on the London Underground? Probably not, although they have the means. I should really not post when I'm half-asleep.
And with that, the thread comes to an end. Goodbye.
