For me personally both white nationalist, neo confederates, and alt right are the core and I use dissident right to describe the broader contingent of people that may overlap with some of our ideas but not line up personally on everything. For example someone that believes in IQ science and the dangers of central banking but isn't necessarily third position and doesn't like ethno state discussions is still a dissident. Another example is EMJ that isn't a race realist publically but very strong on opposition to organized jewry, anti porn, anti degeneracy, anti nihilism, anti Zionism etc. I consider a lot of authors and writers like EMJ, Mathew Raphael Johnson, James Perloff, Ron Unz, Joe Kelly, etc as dissidents and not necessarily white nationalists/alt right. This difference between the two terms is healthy because having extreme ideological purity can kill political coalitions.
