They're orcs. They're not human.
Look at cats. Look at dogs. No matter how very different an individual cat or an individual dog can be, ALL cats have certain behavioural traits and ALL dogs have certain have certain behavioural traits.
So we can say all humans have certain traits, and all orcs have certain traits.
When you think of orcs as humans, it's like you're saying "a golden retriever is superior to a dobermann". Now that is silly, and I understand how it can be considered racist.
But when you do not think of orcs as humans, you're saying "dogs are different from cats" which is true.
In fact, I shouldn't call them a race, so I could make my point clearer: I should say orcs are a species.
Again, I understand my cultural background is very different from that of an American, so there's some things I say without realizing they may be perceived differently by another culture like America's. So let me make it clear, I see orcs as a different species. I don't want any comparison with human phenotypes. If I wanted that I'd just make a town of humans and make them warmongers or whatever.
This is also why I describe orcs as savage and such: I intend they ARE quite literally beasts.
