I've also argued against them looking objectively savage. If you agree that savage appearance cannot be objectively identified, then there is no point in arguing about it.
I am really confused about how you're making your point.
However, I will point out that they are objectively savage in appearance and biology.
The Human's special ability is
leadership. The lizard's special ability is breathing fire as an attack. The lizards have sharp claws, and a large mouth filled with carnivorous teeth. This is indisputably violent, therefore savage.
In fact, humans are easily the least violent or savage out of all the races in terms of biology. Dwarves are extra strong and built for damage. Elves are cannibalistic. However, lizards the ones who unambiguously look savage.
