Hippos are defensive. They live in areas where they need to protect themselves from all sorts of predators. They are also extremely territorial and
have anatomical mechanisms to defend themselves. They are also closely related to Cetaceans, which are carnivores for the most part. And which were
carnivores when they lived on land.
Xenarthrans have the lowest metabolic rates among the therians.
Xenarthra includes the anteaters, tree sloths, and armadillos, as well as the extinct ground sloths, glyptodonts and pampatheres. In the past, these
families were classified together with the pangolins and aardvarks as the order Edentata (meaning toothless, because the members do not have front
incisor teeth or molars, or have poorly-developed molars)

These guys are slow. They're not closely related to anything that is carnivorous past eating small lizards. They don't have defense mechanisms
beyond having physical protection. Those claws were not used for stabbing, they were used for pulling down trees.
They also became extinct. Obviously they did not evolve well enough to protect themselves, and it looks like humans may have hunted them out.
If it was aggressive or dangerous it would have survived better. If it was able to protect itself against humans, they wouldn't have hunted it to
extinction. (Or supposed extinction.)
I did not say it was not dangerous because it was a herbivore. I said it was not dangerous because it was heavy, slow, with non-defensive claws. I
said that all before this post. The fact that it was a herbivore means that it is not likely to go and eat you, and that it does not seem to have
claws and teeth evolved in such a way as to be a strict predator.
