110,000 UMAP

Version of Opinion cluster analysis of 110,000 people using UMAP instead of PCA
Impression "Like a stingray"
I'm curious if the tail part is a political feature or a systemic one (e.g., people choosing "I don't know" or "neutral" on everything).
If you look at the data, there's a "don't know" for each question, and I'm including that one-hot expression.
If even UMAP can't separate them, there's no way PCA can.
There was some kind of cluster sticking out of the PCA, so maybe that's the stingray's tail.
The opinion vectors of anonymous citizens are not so clearly separated.
