Why are genetically born male and females called this horrible name CIS male or CIS Female, I think that is so degrading?

What are we lower life forms or something. What's wrong with the way it was. It worked for as long as human created langage. I insist that we be called male and female or boy and girl or man and woman. Not this CIS bullshit.
