I didn't say your claims were wrong. I said that they were poorly supported and that you ignore the two much larger reasons that large numbers of people avoid dairy.
As an example of the lack of support:
> igf1 and cancer https://www.ncbi.nlm.nih.gov/m/pubmed/15562834/
I read the abstract. It suggests that circulating levels of IGF-1 may be related to cancer. It does not say that drinking IGF-1 is related to cancer or that milk contains absorbable IGF-1. In fact, I found one study that determined that IGF-1 in milk is broken down during digestion and that mechanism by which various dairy products might impact blood IGF-1 levels are unknown.
So I maintain my claim that all the reasons you listed are poorly supported. In contrast, the fact that most people do not have the lactase persistence trait and end up lactose intolerant as adults is very well supported indeed. Similarly, I know people who have done genuine lab tests and determined that they have bona fide IgE-mediated milk allergies. Apparently some people also have non-IgE-mediated immune reactions to milk. Of all of these, among adults, lactose intolerance is far and away the most common issue with dairy products.
BTW:

If you want to drink milk or eat cheese that is cruelty-free, there are quite a few purveyors in Northern California that have cows that are very happy indeed. If you ever want to feel jealous of a cow's living conditions, just drive near any of the dairies in Point Reyes. Some of them offer tours, and others will let you just drop by and say hi to the cows. I'm sure there are plenty of places like this outside Northern CA, too. Obviously, you'll pay a bit more for this milk, although, the cheese doesn't seem to carry much, if any premium. I suspect the latter is related to the reduced costs of being a Class B dairy that produces cheese in house.
