The milk message has been one of those, where the implication is often that you don't need milk as an adult. There are many memes about how odd it is for humans to be still drinking milk as adults, or claiming milk is for babies, or that it is questionable for men to want milk etc? I see those a lot.
I am really confused at what you're trying to say here.
Milk as in mammalian milk
is for baby mammals. And adults do not need it. In fact the default is that adults are lactose intolerant. In the west where we drink a lot of mammal milk that got reversed.
Milk as in the squeezed juices from plants is fine (perhaps not the milk from a rubber tree

) . But completely different.
I see nothing wrong with this argument.
Or the "cruelty free" message - pretending that vegan diets mean no animals are harmed or killed.
I think the cruelty free message is fine.
No, of course animals get caught in the crossfire, and many are purposely
removed for crops. But compared to breeding new animals with one goal in mind, it is cruelty free.
But I do get what you're saying.
Many people have claimed a vegan diet is the healthiest, yet that's open to question with most authorities and evidence pointing to a Mediterranean style diet as the healthiest. A vegan-friendly diet can be healthy, but it does require knowing what you are doing - it's not healthy by default.
It really doesn't take much knowledge. That's myth. I was taking supplements before I went vegan. I still do. So my fairly default (no meat, eggs, milk) diet
is healthy by default (aside from the Beyond burgers etc).
The average "American diet" is way less healthy than even an unplanned vegan diet.
Basically all humans who do not plan carefully, vegan or omni, should be taking at least multivitamins.
But yes, the Med diet is considered also very healthy. But then veganism is not about health primarily.
The use of human-centric terms to describe what happens to animals in farming.
I agree on this.
I dislike the terms "rape" and "murder", especially the first one, which IMO is very insensitive to people who have been personally affected. i.e. Comparing artificial insemination to rape is at best, callous.
"Murder" is an odd one. I mean it's defined as unlawfully killing another human. And the equivalent animal term "slaughter" IMO sounds way worse!
There are more examples like this. My point isn't that these are directly wrong, but that they can easily be dismantled or even illustrate a lack of genuine commitment from those making the claims. All of which weakens the vegan message.
Yes. I have said for years that we should always strive to tell the truth and not exaggerate or sensationalise. It detracts from the very real horrors of animal farming, especially factory farming.
There is literally no need to do this. The truth is horrible enough.
