If WP can't keep the Orcs at bay, the day is coming when all the articles will be red-mattered like Vulcan in ST 2009.

In the original case of the orcs' Black Speech in Tolkein, they were a race incapable of saying anything pretty because of their language.

Unless the people are humans or elfs (hence orcs) or dwarfs or hobbits - then they aren't influenced or changed at all by the power of the ring.
