Ya'll misunderstood my post about infidel. I expressed it as a religious pejorative only to provide an example of its use. As I said in one of my previous posts on the subject, Vito used infidel to express his dissatisfaction with Sollozzo. Such dissastisfaction could have subsumed Sollozzo's involvement with drugs, or his polygamy, or his association with the Tattaglia family, or all of the above.
