The gaps in views are certainly widening in societies in general, but my point wasn't exactly that. It was more about differences which always existed. When I was young I was often dumped into large family gatherings which lasted days (birthdays of (grand)grandparents, funerals, weddings etc). I had to practice handling cousins etc who might had very different family backgrounds than me since very early age. We had to find things we had in common and accept our differences. We learned that differences are manageable. It's not common nowadays. Many people don't have relationships with relatives at all and kids don't meet another kids with different background until school. And even then distance is kept often because of overprotective parenting.
