There are aspects of "Kosher" that are not "Rabbincal" tradition. Such as refraining from pork and shellfish.
I prefer not to use the word Kosher or kashrut.
It only confuses the Goyim.

No, it does not confuse the "goyim".
You said that the dietary laws were rabbinnical tradition and not scriptural.
And then you agreed they were scriptural.
So, do you keep them?
It's a simple question.
There isn't anything confusing here.
