“to assume that you _probably_ hold conservative beliefs due to having an interest in guns is way more often the case than not“

Only in the crudest statistical sense. For example the fastest growing demographic of gun owners is black women, who are overwhelmingly Democratic voters.

And that’s exactly what the complaint about these algorithms is.

That these algorithms are crude statistical approximators of hidden latent biases in the training data? That's their entire method of functioning! That's the entire process of a neural network. It seems you're wanting something that can predict the future, which is currently outside of our matrix multiplication skills.

I’m not ‘wanting’ something.

I’m simply pointing out that the algorithms do in fact steer people towards polarizing content, that is not what they would have otherwise chosen.
