Jews have learned over the millennia to keep it, not secret, but kinda on the down-low.
Also, not being a proselytizing religion, not much reason for them to "identify." They don't want to convert you.
I know a lot of Jews (they're heavily over-represented in law in the U.S.), and I'm pretty sure I've never heard one call you (or anybody else) a "subhuman goy."
But you go ahead and make up whatever you need to.
I remember some satire of the heavy-metal types, with the lyrics
We're coming
We're coming
We're coming
Here we come!
We're coming
We're coming
Screaming at the top of our lungs!
