Why do people use the term 'anti semite'?

It's a term used by those that say they are Jews and are not. It is a term used by those who are at the head of corruption and murder and don't like the light Shawn upon their evil ways so they invented a word that even if you try to suggest that the fake Jews are guilty of atrocities and genocide they pull out that word and you are know considered a vile racist or worse.

Those that hide behind that term are the same ones who put the poor God loving Jewish people in the camps in nazi Germany and funded it too. Screw that word and what it stands for. The same banking cabal that is enslaving the world in debt is the same cabal that put that illegal state of Israel where it is. God knows who they are and what they've done.

The word Semite was originally used to describe a group of various peoples in the middle east that spoke a Semitic language, which included Hebrew, the language of the Jews.

So the term is used to describe other peoples? I see people being called anti Semitic without saying they hate Jews. But the fact Semite isn't exclusive to Jews make it even more bizarre because why would anyone hate a peoples with a lineage? Seems like the term is misused beyond recognition.
