@DANIΣL Here are my responses to your most recent message.
1. You can laugh at Haidut's thread title that "All Gut Bacteria Dangerous" all you want, it still doesn't make it inaccurate. Are you aware of the definition of the word "dangerous?" Here's what I get when I type it into Google for a definition-
Adjective, -able or likely to cause harm or injury. Second sense -likely to cause problems or to have adverse consequences.
Hmmmm. Based on those definitions, and the content of the thread, it would appear accurate. Replacing the word you're hung up on with the definition, we get "All Gut Bacteria able or likely to cause harm or injury" or "All Gut Bacteria likely to cause problems or to have adverse consequences." Both statements are accurate in the context, especially when he spells out how they are dangerous in the second part of the title (by their production of endotoxin causing liver cancer). He didn't say "Acutely Lethal," which would have been wrong. Basically, gut bacteria are dangerous in the same way plaque in the arteries are dangerous.
If you aren't hung up on the word "dangerous," are you claiming that some strains of gut bacteria don't produce endotoxin?
2. Your claim that "no human has ever had a sterile gut" is flat out wrong. Guess you don't know about David Vetter, aka The Bubble Boy?
More practically, Haidut has cited the example of humans that are on long term antibiotics for things like Lyme Disease, that develop a Sterile (or 99% Sterile) Gut as a side effect of the treatment. Those would be more applicable, as basically no one would choose to live in an isolater like Vetter did, and certainly can't do so retroactively since their birth.
3. I agree that antibiotics should be approached with caution, although I wouldn't go so far as to say "last resort." I do think some of the dangers of antibiotics are overblown. Note the use of the word "danger." That said, I think antibiotics are dangerous too, hence why I said caution in the first sentence of this part.
4. I don't think antibiotics are the only or main factor in gut dysbiosis, certainly not in the US. As a major factor, I would point again to iron in my earlier post, especially supplemental iron like ferrous sulfate. Especially worrisome is the iron found in infant formulas. I think there are benefits to breast milk far beyond bacterial content, maybe even in spite of any bacteria that does appear in breast milk.
I think formula feeding probably one of the major factors in dysbiosis, expecially with so much free iron. 1.8mg in 5fl oz, with no protections like you might get if you ate spinach or beef. Milk (all sorts) has virtually no iron. Infants generally don't need it, they are born iron loaded, which is good, as they "grow" into their iron stores. "Exposing the Hidden Dangers of Iron" by E.D. Weinberg goes into greater detail about this, and details some of the more horrific experiments where otherwise healthy babies die as a result of getting an injection of Iron Dextran.

5. C Section is a stressful way to be born. Neither Haidut nor Peat recommend it, and I don't know if it has much to do with the so called "beneficial bacteria of the mother," though I know I have seen that claim elsewhere. Vaginal birth is certainly better in a number of ways. Same thing with Breast Milk, I pointed out the issue with formula, which most parents use as a substitute nowadays. Using cow or goat milk might avoid some of the formula problems, again many which have nothing to do with so called "beneficial bacteria."
6. You shouldn't make assumptions about others. I have been on the "other side," back in my Paleo days. I tried probiotics like Prescript Assist, ate raw potato starch for the Resistant Starch, drank kombucha, even made my own kefir from raw milk, and saurkraut to boot. I'm not really interested in that so much nowadays, and like I said, I have found much better success personally from things like Antibiotics and AC.
7. You really do seem to be more interested in the concept of the microbiome. That's why I suggested you start a thread. I didn't mean just post a bunch of studies that you didn't read. But a thread, similar to the way Haidut does it, where he posts the study, gives and overview and quotes, and then his own take on it. I think that would be more valuable in general.
By the way, did you look at my thread on how Peat talks about the benefits of lactobacillus bacteria to the gut....... even if the organism is dead? Posting again here in case you missed it-
Probiotics- Better Off Dead. (And More Effective!)
One of the ideas of Ray Peat's that seems to run counter to both the mainstream and alternative health world is that bacteria in the GI tract is NOT beneficial, in general. Peat has said that there are some strains of bacteria that are less harmful than others, and even can produce some...raypeatforum.com
Here's the clip that leads it off, you should at least listen to this part-
Have you researched the Shikimate pathway?
