"Saudi" is not just a demonym like "German" or "Chinese" but a specific political program, and even a specific small set of extremely bad people. Fixing that would not make a "free Saudi Arabia" in the way we might imagine a "free Tibet" but literally a different country not named after their psychopathic kings.

It is not xenophobia to acknowledge it's worse to do something dumb which enriches your ideological and material enemies than to just do something dumb.
