Centrism means not indentifying with neither the left of the right. And so, I am a Centrist because I am too pro-capital to be left-wing and too welfarist to be right-wing. The cultural axis doesn't determine if someone is Centrist or not, I know a guy named Banned who claims to be a Centrist but wants to go back to the middle age. And I only choose "Culturally Center-Left" since it's the closest to my cultural policy, because ideally, I am a bit "Libertarian" in the sense I don't want the state to involve itself in culture.
And I don't think I am too similar with DECB. He is a pseudo-libertarian, I am a statist. He is a Neoconservative, I am non-aligned (in the sense of Tito's NAM). And he is very progressive and internationalist, while I am moderately progressive and nationalist.
