Well that is the point of the post, isn’t it? Right winger supporters are swallowing corpo/oligarch manufactured propaganda promoting racism, misogynism, ageism and all other sorts of bigotry against outgroups as the reason for their political ideals.

And it is all constructed to obfuscate against the real issue of class war. But actually understanding that issue requires complex thinking of how society actually functions (a lot of people aren’t even aware that they are working class for example), while biogtry reduces the problem to a very simple us vs. them explanation, which even the most moronic person can understand.
