They're very different. My grandpa killed himself, the Aryan race was his favorite animals. Whilst Steve Irwin dies form a sting-ray. Very different. Steve Irwins favorite animal was the saltwater crocodile, still different.
PETA is actually an acronym for "People of the Ethical Treatment of Animals" Steve was a nice guy but PETA says that he died harassing a stingray which is messed up.
