Right. Who's funding this.
So there are multiple groups with overlapping interests.
The Russian regime aims to paralyse and destabilize the US, UK and other countries which might get in its way. It does this by attempting to widen division and internal strife. Putin and friends would also like other governments to be supportive of their kleptocracy (no meanie sanctions against individuals) and of Russian actions eg invasion of the Ukraine. Nationalism, homophobia and racism in various flavours are popular motivating themes in Russia. Russia has plenty of dosh to throw at this - but actually troll farms and botnets are much cheaper than old-fashioned methods of influence.
Another group is the so called alt-right. Basically Nazis with new technology. They tend to have a pick'n'mix from the usual Nazi basket: anti-Semitic now also anti-Islamic, extremely racist, immensely misogynist. Good supply of keyboard warriors. Obviously common or garden MRAs find happy resonance in some of this stable's output. In general, keep an eye on Milo Yiannopolous, Steve Bannon, Richard Spencer.
You might think the alt-right are guys in their parents' basements, but in fact they overlap with the next group, economically very right-wing. These can be US-style libertarians who have an idealogical belief there should be no government regulation - specially no regulations that inconveniently stop them exploiting poorer people. They can be disaster capitalists, who love a good hurricane or Brexit or tech revolution, as it disrupts the existing order and allows them to swoop in and make a quick buck or re-write the rules in their favour while everyone else is trying to catch their breath. Many of this group are, surprise surprise, extremely rich. They're happy to throw money about.
Special cases of the above are US billionaires Robert Mercer and his daughter Rebekah. Mercer père is also ideologically racist and from the tech industry. He funds Breitbart, which employed Bannon before possibly during Bannon's stint in the White House .
Then there there's the so-called religious right in the US. They're engaged in a continuous fight against abortion rights and many aren't too keen on women having access to contraception or men being prosecuted for rape (unless it's the Wrong Sort of Man, obvs).
Then there's the tech giants. Don't know where the balance is between them trying to take charge of the world for idealogical aims, and trying to take charge of the world to make lots of money. I'm sure it will vary. They have reyther deep pockets.
I'm sure I've left some out.
Many of these groups have clustered around the Brexit referendum and Trump presidency, as OPPORTUNITIES for their agenda. The disruption and (in Trump's case) malleability of key players are wonderful for them. They cover their tracks by deflecting all scrutiny as "sour grapes your team didn't win." In the UK, keep an eye on Farage, Arron Banks and friends, Carswell, perhaps the Chandler brothers.
Although I've talked about right wing groups, I'd expect there to be Russian and other funding of ostensibly left-wing groups towards some of the same aims. So that's something to be aware of in coming years. Similarly I haven't tried to see how Islamist extremism fits into this, but it's certainly in a symbiotic relationship with the Western ultra-nationalists and religious right.
Promoting anti-woman transactivism fits in very nicely with the agenda of lots of these groups. The Russians like the division and the distraction from their own activities; the neo-Nazis like the misogyny; the cut-price MRAs like that too; the billionaires like the disruption; and the tech firms like the clickbait. The religios right... they may be on the horns of a dilemma about who to hate most...
That's a whistlestop tour, and just my take. I could be wrong or have missed important chunks, and I know the broad-brush characterisations leave a lot to be desired. And I hate sounding like a conspiracy theorist.
But basically, this is why Russian-owned botnets were retweeting alleged rapist Julian Assange's prolific tweets promoting Catalan separatism.
If you're fighting within a single cause, eg women's rights, the Assange-Catalan thing looks like random nonsense. It's only when you stand back and take the whole view that it suddenly makes sense.
