I don’t think racism itself is enough for Trump and far-right to succeed, which is precisely why they’ve combined it with populism and working class rhetoric. Of course, there’s still racism like how muslims are being portrayed as violent beasts as opposed to culture white christians, but a lot of it is also things like “immigrants are taking away money from welfare thats why you live bad” or “immigrants are taking our jobs” or “jews control everything and steal from workers” and so on, you know what they say.
Like any good right-wing propaganda, there is a grain of truth in those statements, and it’s that economic reality of working class is shit - wages are stagnant, exploitation is rampant and just pure stress when it comes to finances. I do believe that if people’s needs are met then the racist rhetoric would lose a lot of its power and people will just stop caring as much as they do right now, but that’s very unlikely without any radical action.
