So the problem is that you can make some statistical predictions about what someone's views are based on their reading habits. But you can't morally judge them on that basis because you don't (and can't) know why they read something and what they thought about it. This is similar to how BMI is commonly misused. BMI is a fine indicator of population health, but is not always indicative of individual health.
To your example of BMI, it would be a perfectly reasonable public health policy[0] to use machine learning to probabilistically identify persons of an excess BMI to send them pamplets and resources for weight loss / exercise. Will the odd fit person get a letter from the surgeon general telling them "being a fatass is bad for their health"[1]? Of course. I don't see why that is a terminal problem.

But also, a few people are obese because they are on steroids or they have some genetic issue independent of their choices in life. They are not the norm, but they'll get lumped in with the norm and that's offensive and improper. That said, if FB found out their userbase is unusually obese compared to the rest of a country's citizens, that informs them they have a potential moral hazard in their hands.
But if you're deeply offended at such telemetry, maybe consider no using Facebook. You'll be fine without it. I personally make sure to post ridiculous and contradictory responses to the insipidly and horribly targeted ads they push into my feed. Some of them have gotten me suspended for violating their "community standards" that IMO would not get me suspended anywhere else.
Companies are making these kinds of flawed assumptions about you and every one of us every single day. They often then sell that info to data brokers who happily sell that data to others who will then start with incorrect assumptions about you as an individual and let that influence how they interpret the rest of the data they collect about you.
It's a real problem because those flawed data sets you aren't allowed to see, contest, or update are increasingly being used to meaningfully impact your everyday life in ways that you'll never be aware of.
The bottom line is that companies don't care. If they will make more money by being right most of the time that's what they are going to do. You might be the fittest, healthiest person on Earth, but if your health insurance company sees that people in your area code have started buying fast food more often they can decide to raise your rates. They won't tell you why they did it. They'll just do it. You could be the most financially responsible person on Earth but if you live in the wrong zip code don't be surprised when you get denied certain services or told that a company's polices are one thing when they would have told you they were something else if you lived on the other side of town.
That said, it's probably a whole lot easier to make accurate predictions about people than you think. Sure you'd read fox news, but most of your time is probably not spent on right wing sites, you probably aren't leaving comments espousing right wing talking points, and you probably aren't donating money to right wing causes.
With enough data it's not that hard to figure out if you're regularly hanging out at stormfront because you're working for the Anti-Defamation League or because you're a racist.
Algorithms can detect (and exploit) mental illnesses like bipolar disorder and Alzheimer's companies can certainly detect "stupid" well enough for their own needs.
So you read conservative blogs and listen to Fox News. If Facebook is predicting, for instance, your voting habits, their algorithm won't look only at that. It'll look at where you live, what your job is, the political stances of the people you most associate with, which groups you're a part of and how their members typically lean, what stores you shop at, what search terms you use, and far more metrics than I can list here. Can you honestly say that all of those will point to incorrect conclusions? If you somehow live a live entirely contrary to your internal beliefs you're in a minority so small as to be irrelevant.
My politics are idiosyncratic and lean far enough to the left that I have a hard time explaining them to my centrist liberal friends.
At the same time, I read a lot of far-right sources; I do not find them at all compelling, but in addition to the fact that I like to know what the people who think I am a literal baby-blood-drinking demon might be up to, I have an MA in rhetoric and find the discourse to be as engaging as stuff like William Burroughs or The Illuminatus Trilogy...
And I am not alone in that. You simply can't divine much of anything based on their search history and reading list, and that's made even more difficult by the compartmentalization that some of us are using in0-browser to work against tracking.
Yes, 100%. How can it, if we agree all human life is sacred? Are some people more sacred than others? Holier than thou? (getting downvoted for this)
All men are created equal. Ashes to ashes, dust to dust. Ephesians 6:9 "Slave owners, you must treat your slaves with this same respect. Don't threaten them. They have the same Master in heaven that you do, and he doesn't have favorites."
But that wasn't even the original term. The first comment in the thread was about whether people are "stupid and superstitious".
So pretend the question was "Do you think what a person reads has no predictive value on how stupid and superstitious they are?"
Prediction isn't assigning.
And nobody in this comment chain said anything about banning. In fact the OP specifically said "I don't see a solution to that any time soon."
(My prerogative to assign cognitive attributes to you derives not from your choice of reading material, but from your apparent inability to realise the above.)
The opposite position could be practical in certain societies. A Mexican parent would encourage having the baby. In other areas with more traditional values it might be more practical.
Whatever position you have could be moral or practical or cyclical or spiritual.
