The political compass is a better representation purely because it acknowledged that political ideals aren’t a linear spectrum, but it still misses the mark because a plane isn’t sufficient either.
Politics is such a complex topic and any simple representation of it will lead to what would appear to be contradictions in a person’s beliefs.
My only point on the compass being a better representation is that it acknowledged a problem. That’s not to say it’s a good representation.
I think it’s unhelpful to say that a step toward more fidelity is the same level of bad, though. Even if it’s the tiniest step, it’s a move in the right direction by pointing out that a single line isn’t sufficient.
In reality, it would be more like a series of lines on different topics weighted differently by an individuals priorities so no singular generic representation will ever be truly good enough.
