Mercyandjustice,
If you mock the Old Testament and its words, then you are not Catholic for you despise the word of God.
The fact that you cannot understand Our Lord's decrees is not a reason to mock them. All impure animals were less healthy than the pure animals: pork is the best example. Well, the Messiah was to be born among this people, who had to live in purity of soul and body - otherwise the Messiah could not have been born among the Hebrews. Many of these men had a better life and were less lustful than all those Catholic who despise the Jews of old times and who feel so great.
Most people were stronger than us at that time because they lived in chastity and their children were strong. Even some Pagans were more chaste than the Catholics of today. One day I have seen a French docuмentary where some French people went to live among some primitive people still in existence; and when of these women was asked about sɛҳuąƖity, she said that she had had intercourse with her husband one single time, to have her child - and the rest of the time, she refrained from doing so. The reason is that this tribe had not much food in this place.
If some Pagans have a better life than us, we will blush before our Supreme Judge.
