I agree. I think they're very good at it though. They argue that because they've always been on the fringes and unofficial (as has a lot of left wing thought too) that they are practised in the ways of "alternative media". They're certainly very good at simplistic propaganda - see the Meme war stuff around Trump, and it's interesting that that was less successful in non-English speaking European countries that have a more sophisticated political culture.
Their arguments are always simplistic - someone else's fault! (I saw an Alan Moore interview the other day in which he called fascism, the ultimate failure to take personal responsibility to paraphrase) - and work well. They're also very effective in their assault on objective truth and are cashing in on a wider disatisfaction with "elites" and "experts" - not just in the sense of the wealthy and powerful, but also academics, researchers and cultural figures.
I think it's fair to chuck in Russian influence too - though their operations are said to promote extremes and division as much as they pick a side, so in the US they've been found to be behind White Nationalist Texan seperatists and some fringe Black nationalist sites too.
