"whole milk" is often skimmed, or occasionally, added to to make it fit in a certain legally defined bandwidth of fat content. It's not unmodified.
Also, homogenization absolutely changes the texture of the milk. That is in fact part of the point, making sure nobody gets the crappy milk. Some people prefer it, some don't, it's a personal taste thing.
Okay, sure, they skim it. But your original comment was worded a bit badly, the way I read it implied that whole milk contains 3.25% of all the fat that it should if it was truly whole, rather than that it contains 3.25% whereas true whole milk is just slightly more. Some people do believe that whole milk is actually 100% fat which is why I thought it best to correct you.
I do wonder why they have such a precise requirement for whole milk in the US. Where I live, most whole milk sold is roughly 3.5 to 3.8 percent, and often they actually give a range instead of an exact value on the package. I could buy a carton of milk that says "3.8% to 4.4%" if I wanted to. My personal preference is "whatever's cheaper, but if whole milk isn't much more expensive, go for whole". Usually I use it in food rather than drinking it straight so the flavor doesn't matter as much to me.
Oh no, yeah totally. I definitely just misspoke in my original comment, and instead of simply correcting it, I've been doubling down and twisting it so it seems like I was right and that's what I meant the whole time. That's definitely what I was just doing lol.
