Let's not forget the similarities between the Kinsey "research" and the recent "fetal pain study." That is, "researcher bias," or the justification of perverse behavior with scientific language. What it comes down to is that for the Kinsey "researchers", "When I touched them, they liked it!" Similarly with the abortionists: "When I dismembered them, they didn't feel any pain!"
John Paul II (and many others) have remarked that we do not see the evil and injustice of sin when we sin against others. It is only in contemplating the sins that are committed against us that we understand their gravity.
