He literally just stole all his talking points from Richard Spencer and Chuck Johnson.
The things Fuentes is saying right now are things Spencer and Johnson were saying all the way back in 2020 and even earlier.
Fuentes flip-flopped in 2024 once he had realized his current pro-Trump MAGA grift had ran its course. After Trump had ejected him and Kanye from the White House he knew the doors to the Trump admin were for ever shut, and so he simply rebranded himself as an anti-Trump guy (like Spencer in 2018).
Nothing Nick Fuentes does politically comes from any sincere conviction, nor does it consider what's best for the USA.
Everything he does is driven by self-interest; fame, clout and money.
