Ketubot 15a discusses the case of A killing B, when A actually intended to kill another person. In its discussion the Talmud refers to “Canaanites”, which in the current context simply means non-Jews. In fact, in all manuscripts and early printings what appears is not “Canaanites” but “goyim”. “Canaanites” is simply a “correction” of the censor. Yet ArtScroll has a note explaining that “The Canaanites were the pagan people who lived in Eretz Yisrael before the Israelites entered the land.” The implication of this comment is that the halakhah stated in the Talmud was only applicable with the ancient Canaanites but not with regard to other non-Jews. This is false and ArtScroll knows it is false, but it is no different than the “note to reader” found in many seforim that all the halakhot about non-Jews only refer to the pagans in faraway places. In the latter case everyone knew (and knows) that these words are not to be taken seriously, but I would assume that the typical user of the ArtScroll English Talmud does not realize this. It is noteworthy that the ArtScroll Hebrew Talmud does not include the note about the Canaanites.
