Two things:
One: Before retiring, I worked with many, many Protestants. In fact, there were few Catholics where I worked. Virtually all of the Protestants I worked with used the King James Bible exclusively even to the point of claiming that other versions of the Bible were inspired by Satan (especially the "evil" Catholic Bible which, they would tell me, the Church forbid me to read :o). When referring to the Third Person of the Blessed Trinity, they never used, "Holy Ghost." By the way, the place I worked was the U.S. Army and those Protestants were from throughout the United States.
Two: Today, I view the Holy Ghost/Holy Spirit issue as more a political question. A person today who usually uses the term, Holy Ghost, identitifies himself as a Traditional Catholic. The person who usually uses the term, Holy Spirit, does not identify himself as such, though I would not say that he idenitifies himself as a Protestant or a Novus Ordo Catholic; he merely is clearly not identifying himself to others as a traditional Catholic.
