Where do we go with the love of animals?

My son, student of multimedia and veterinary medicine by love of animals, is vegetarian. He has, by that, a less diverse nutrition than mine and my wife’s. So, he is a concern for us both. That fact, some days ago, motivated the following conversation between me and my only son:

Son, you must do how Jesus Christ and the Apostles because they never got used to eat meat. But they always ate fish and bread. So, don’t eat meat, if you don’t want to, but eat fish, son! You would do very well.

Oh! Father!! I can’t because I pity animals.

Me too, but I eat meat… Yet, I would fain to be the standard-bearer of all the wild and domestic animals. In your great-grandfather’s farm I did the birth of countless calves but it isn’t the reason why I love animals. I love them because they are the weak, the weak and the oppressed. I don’t like the strong that don’t set an example. I hate the strong when he makes fun of the weak or mistreats him verbally. Even though the weak is indolent and slack. I loathe the student when he is rough with his teacher (the teacher should be, always, the loved one). The care of the weak is innate and instinctive on me and on many other people, son.
