"...Wesley Morriston agrees writing that there “is nothing uniquely “Canaanite” about them. All, or nearly all, of these practices—from sexual intercourse during a woman’s menstrual period to homosexual behavior to bestiality—are still common. Is there any real reason to believe that these things were more common among the Canaanites in the ancient world?”
"More likely it is that the biblical authors are deliberately depicting their Canaanite enemies in a negative light, thus portraying them in a way that is not entirely fair. One should remember that the Israelites were the supposed exterminators of the Canaanites and we only have their testimony bearing witness to the Canaanites themselves. We have to rely on the killers of the Canaanites to learn about the Canaanites."
