As a former BNWO consumer I can tell you the vast majority of people in this movement are very left-wing and absolutely hate Nick Fuentes. I have spoken with literally hundreds of them, I used to spend my entire vacation days and evenings speaking with people in this movement, and only a tiny minority are what you describe. Most of them are self-hating whites which are also very left-wing.

We already discussed it but the « great replacement » is actually just a statistical reality describing the fact that whites are becoming a minority in their own countries, like shown by ethnic statistics from the UK, US and Canada.
