Society is measurably more divided now than anytime I have been alive.
There were always sharp disagreements, and always condemnations from one side to another, but the number of people who have such sharp disagreements keeps growing.
The most striking measurement, to me, is how the number of people who would accept if their child married outside of the parents preferred political party keeps going down. All other kinds of acceptance are going up. People are more tolerant of racial differences, people are more tolerant of homosexuality, people are more tolerant of other nationalities and religions. But not political differences. "Son, I'll still love you if you marry a man, but he better not be a republican!"
