I always checked sources where I could, but I never noticed how both grassroots and bizarre propaganda efforts were until the 2016 election when you could literally go onto somewhere like /pol/ and see the crafting memes by committee and making them seem legitimate while knowing they are not. I mean, you have everything from Joe Rogan claiming the SPLC is out of control today on twitter because he believed the people he met over sourced fact checks that show they lie about their history to Louise Mensch and Kim Dot Com being primary sources for news.
A part of why so much propaganda is crude and obvious is for the same reason as why so many email/phone scams are crude and obvious. They’re deliberately selecting for poor critical thinking and low scepticism.
Avoiding Twitter/Facebook/etc will help to personally avoid the most intense stuff, but be aware that essentially every major journalist on the planet is a Twitter addict themselves.
