I’d say that, if you are lucky enough to be born, by pure chance, in a great family with loving caring and respecting relatives, than the amount of support, financial and non, you can get from that kind of Italian family is amazing. I know people who gave up good careers abroad and moved back to Italy for this reason. However, these situations seem somewhat rare. Cases of overbearing, suffocating relatives and extended family seem way more common. It would be interesting to ask Italian divorce lawyers how many of their cases are caused by MILFH (no, not MILF, but Mother-In-Laws-From-Hell)!
As for Italians being more respectful of other opinions, I am not so sure about that. Populism and social media have had a nefarious effect; it is now very common for any idiot to turn into a keyboard warrior and take his/her frustration out on experts because he/she has read something on the internet. We saw part of that in Brexit, too, but Italy’s government is run by a weird coalition of the League and the 5-star-movement, next to whom Boris seems like an accomplished diplomat. For example, the anti-vaccine movement has been gaining ground over the last years. One medical doctor, Burioni, who has been very active on social media debunking all the fake news against vaccines, has received death threats and was forced to cut his holiday short because people had been following him and posting his whereabouts (we know where you’re staying, you can’t hide, etc). That is sad and scary.
Italy’s largest daily, Il Corriere della Sera, provocatively talked about the “5-million club”: in a nation of 60ish million people, approximately 5 millions regularly read newspapers, buy books, watch the equivalent of BBC’s Panorama, etc. Everyone else? Most likely keyboard warriors, or at risk of turning into one.
