I'm pretty sure "most" is not accurate. Over 50%??? Are you sure???
We have a niece married to a 1st generation Italian . His father told her that that a man taking a mistress does not mean he does not love his wife..
Remember the reaction of Europe to Clinton? They thought we were "provincial "
I do not know if even 50% of Italian men are married (marriage is on the down turn there too according to some current events programs .)
But as my niece was told Mistresses are a cultural practice.
Europeans are disinterested in the things of God. (Not all but many perhaps most..if we look at the 30% number for church attendance).
That is why they are willingly inviting Muslims (that are not indifferent to allah) into their countries IMHO they do not understand or perhaps even remember religious zeal..God will make them remember me thinks
