Crazy idea, but maybe you shouldn't be taking health advice from random people on the Internet anyways. And your final line "well, guess it's time for another migration" isn't great either. You're basically saying you just want an echo chamber to agree with you.
I don't agree with carnivores or vegans, but I do find it interesting how vegans will complain about carnivores being biased and then post links to sites like veganlife.com and act like those aren't biased too.
The simple fact is that you can't do proper studies on diet. It relies far too much on self reporting since actual rigorous studies just can't be done. You can't control someone's diet for 30 years to create experimental groups, control groups, etc. it's just too much to ask. The vast majority of diet research is "best guesses" and "there seems to be a correlation here".
Look at the old "Mediterranean diet" craze. The general consensus is that lifestyle(less sedentary life), better public healthcare, and a whole host of other factors related to people living in the Mediterranean are the causes of longer lifespans. But instead it gets boiled down to "eat like they do and you'll be as healthy as them".
Same with the whole "wine is good for you - look at the French!" Yeah, turns out alcohol isn't really good for you at any level. It had a hell of a lot more to do with the lifestyle than specifically wine.
Or "people who stand barefoot in the grass for an hour a day are healthier" becoming "walking around barefoot in nature makes you healthier". Nope. Being privileged enough that you CAN stand barefoot in the grass for an entire hour doing nothing else daily means you can afford many things that others cannot. It likely means that your baseline stress levels are way lower because you have the free time to be able to even do it. You think the person waking up at 5am to go to work until 5pm, to turn around and cook and clean, and then maybe get an hour to theirself before bed is able to just go stand in the grass for an hour? Again, it's way more about socioeconomic status than "touching grass".
The point is, health is an incredibly complex science and ANYONE claiming to have the magic solution is lying or just wrong. And that's all I see here: "my magic solution is better than their magic solution. I don't need to hear any conflicting ideas, just what I already believe." Maybe fight them with facts and science of your own instead of "ewww carnivore!" Unless you want the rest of us to continue with "ewww, dumb vegan".
