My Pet Peeves- Roman/Greek

One of my biggest pet peeves in Greek mythology, is when people say Hercules. It drives me crazy! The Romans took the Greek myths and changed them around a bit. The Greeks were first. They came up with it all. Yet the Romans get all the credit! Look at this list:

The planets are named after Roman gods, even the ones discovered in this century.
Cupid is the star of Valentines day, but no one knows who Eros is.
Who's the king of the sea? Neptune, never Poseidon.

But when people use the term Hercules in Greek mythology bugs me the most. Doesn't anyone know that Hercules is the Roman form? Does anyone realize that the first super-human hero was Heracles? That makes the plot thicker. Hera hates him even though he was named after her.
Yes, the true Greek name is Heracles. But even in Greek mythology does it betray itself by saying Hercules. It's sad really.
