>I would bet on this being the case in four years
Sure, I doubt the Republican party will be aligned with Nazism or anything like it, but there are new elements (from Trump's side) that want to push it in that direction. I don't think they'll succeed in the long-term, but the risk is there.
>Bannon (and Breitbart in general) are not Nazis
Nazism/National Socialism refers to a specific German ideology. Of course neither Brannon nor Breitbart are aligned with Nazism. But that's obviously not what the parent post was trying to directly say.
Breitbart and Bannonism promotes a very ethno-nationalistic agenda (among other agendas), with elements of various philosophies from the past century. It'd be very ignorant to just call them all Nazis or fascists, but also ignorant to say that because they're not Nazis they don't share any of their views.
Breitbart and Bannon are:
* Very anti-immigration from countries that don't have a high percentage of whites (see Bannon's comments on Asian immigrants, and his and Breitbart's comments on Muslim immigration, Mexican immigration, etc.)
* Extremely pro-Christianity and anti-Islam
* Pro-Zionist, as part of what Bannon sees as some sort of global "war" between Judeo-Christianity and Islam
* Anti-American (or non-conservative) Jews (see Bannon's alleged comments to his wife about not wanting his kids in a school with so many Jews and "too many Hanukkah books", and far-right nationalist Jews like David Horowitz posting articles attacking American Jews like Bill Kristol for not being sufficiently pro-Israel and pro-Trump)
What do you call an ideology like that? No it's not Nazism, but it's ultra-nationalistic and sees a large portion of the world population as essentially being lesser than the populations of predominantly-white countries. Bannon clearly wants America to have some degree of ethnic purity, which is similar to far-right ideologies like the Nazis'.
To be clear, that oversimplifies Bannon's beliefs, as he certainly has a strong economic-nationalist, protectionist, and authoritarian ideology as well. But between almost anyone else who's held so much power in the White House, he's probably the closest we've had so far to a Nazi, even if he absolutely is not a Nazi.
>I wouldn't take anything that comes out of 4chan seriously, as they're known for intentionally riding the line of Poe's law. In the same way that I assume /r9k/ isn't full of obese autistic children who abuse their mothers, I assume /pol/ isn't full of fervent Nazis who hate Jews.
This is an argument Milo and others use a lot. That it's all just ironic or post-post-post-post ironic trolling and most of them don't really believe the shitposts they make. And /pol/ (and /new/ and /b/) did start out that way, with an ironic edginess rather than genuine contempt towards non-whites and women, but starting around 2011 or 2012, /pol/ was slowly co-opted by full-on Stormfronters.
Look at /pol/ today and tell me that they don't have a very sizeable % of posters who genuinely admire Hitler and want a Nazi-like regime.
As for /r9k/, that's more of a mixed bag with a lot more trolling and baiting, but I think you'd agree at least 40% of the regular posters there genuinely detest "roasties".
