Sorry, this guy in the video behaves like a savage. Some people may think, that he behaves like a "sub-human". IMO it is not their fault.

There are a lot of words for this kind of people like ape, savage, animal, beast etc. So I wouldn't use it only for one reason: Some survivers of the holocaust are alive today. It could hurt them, if they hear or read this word again - no matter of the context.

If it hurts this bus-ape - I really don't care.
