I think society has become much more self-centered.  Years ago, while individuals had their own vision, thoughts, and convictions, they were also much more accepting of the middle-ground.  At least when it came to recognizing their own views were not necessarily the only views and there was a certain level of respect in recognizing that.  Today, people seem to be more focused solely on their own perception of things.  To hell with those who feel differently.  I'm not sure exactly why that's the case...maybe the internet, social media, and the recent isolation we've all experienced play into that.
